The Contact Lens! Best Invention Since Sliced Bread

As the development of the first contact lens came about in the 1950's, people who needed correction eye wear never thought that technology and the creation of the first soft lens would be the beginning of visual freedom for America and the world!

Imagine the days when you had no choices, and all that was available were framed eyeglasses. Now some people still prefer this option, but it's nice to know that technology has provided people who don't like to wear glasses the freedom of expression with a variety of lens options. The turning point for contact lenses was back in the 90's when the FDA approved the use of the cosmetic version of soft lenses, and also daily disposable contacts were introduced, which caused the lens vision market to change significantly!

What a great invention, and we are sure to mention that people who lived through the 70's, 80's, and 90's were excited with the introduction of contacts and the variety of options available today! Some may agree that vision wear may be a mandatory element in their lives due to their current eye condition, but for whatever reason, they don't enjoy wearing them. There may be physical, and possibly social issues that individuals go through wearing glasses. With the introduction of disposable lens products, finally those who had no options at one time in their life, are truly happy to say they do now!

Technology today in lens care provides a wide variety of disposable contacts, and gas permeable lenses. You can easily find a toric bifocal, daily disposable lens and for the person looking to add a little change in their look, some great color prescription and cosmetic lenses. The days are gone when glasses are the only choice you have, and with the array of vision products online, and the ability to have these options available at our fingertips is what makes this world so remarkable!

Laser Eye Surgery - Demystifying LASIK

LASIK - A now common procedure

One of the first things that springs to mind when considering corrective eye surgery is the term, "LASIK". An acronym for "laser-assisted in-situ keratomileusis," this rather common procedure is used to correct certain vision problems through refractive surgery.

Since its debut in the 1980s, there have been conflicting stories about what LASIK entails and whether or not it's truly successful.

Laser eye surgery is typically used for those who suffer from nearsightedness, farsightedness or astigmatism. Until the advent of LASIK, eyeglasses and contacts were used to treat these issues, but only served as aids to vision rather than corrections.

Those who have undergone a successful laser eye surgery procedure should find that their need for such aids are extremely diminished or eliminated altogether.

Reshaping your eyes

Technically speaking, LASIK eye surgery reshapes the cornea from within the eye itself using laser to accomplish the task.

If, for instance, your cornea is not shaped correctly to fit the dimensions of your eye, this procedure may be effective. By utilizing laser to extract bits of tissue from the cornea in order to reshape it, the refractive error can be corrected and the visual images will then be focused directly onto the retina, which may eliminate the need for aids such as eyeglasses and contact lenses.

After a thorough eye examination, you'll be expected to choose a doctor to perform the LASIK eye surgery. Once this has been done, you'll be scheduled for a consultation with the doctor to discuss the process, and you'll have the opportunity to voice whatever questions or concerns that you may have prior to the procedure.

Don't wear your glasses for up to a month before the op'

You should expect to be instructed not to wear your glasses or contact lenses for two to four weeks prior to your surgery, in order for the cornea to return to its natural shape, without interference from external visual aids.

When an individual wears cheap contact lenses, for instance, the shape of the cornea is changed, so it's important to remove these and leave them out for up to a month before surgery.

In addition, your doctor will instruct you not to apply any lotions, creams, make-up or other products around the area of the eyes for awhile prior to the procedure.

On the day of your LASIK eye surgery, you'll receive anesthetic drops in each eye in order to eliminate pain. You'll then be placed on a table which is positioned underneath the laser equipment, and the doctor will instruct you to look up at a small blinking light.

During your laser surgery, a special instrument will be utilized to hold your eye open, allowing the doctor to perform the LASIK surgery, while the other eye is protected by a shield.

With a couple of hours you'll be on your way home

After making a small incision, the doctor will then expose the cornea, and apply the laser technology that's needed to reshape and repair the eye. Once accomplished, the flap that was cut open to expose the cornea will be put back into position and will heal on its own, without the need for stitches. An hour or two after the surgery is completed, you'll be allowed to go home.

Depending upon the individual, the amount of corrective treatment that was administered and the quickness of the healing process, what can be expected after surgery will vary from person to person.

Speak with your physician regarding recovery expectations before and after the surgery and follow any instructions that are given, in order to ensure a successful LASIK eye surgery experience.

Mike Spencer reviews reviews leading, and sometimes controversial, approaches to improving and protecting our health. Here he looks at the pros and cons of LASIK eye surgery and whether it can offer any real benefits to improved vision.

Dry Eyes and Contact Lenses Don't Have to Be a Parched Pair

Contact lens wearers have long suffered from dry eyes, however dry eyes do not have to be a symptom you live with. There are many solutions to erasing the problem that allow you to enjoy wearing your contact lenses instead of dreading it.

Dry eyes can occur for a variety of reasons, some which may be attributable to contact wear and others can develop for other reasons. If it's a result of contact wear or overwork, you can simply switch lenses or wear your lenses for shorter periods of time. However, if you have dry eye syndrome or an eye disease, your doctor probably has more suggestions for you.

First, you should determine the cause of the problem. Is it environmental factors, related to contact wear, or something else? Once you know what you have you will better be able to treat it.

Artificial tears are often time the best remedy for dry eyes. Artificial tears are simply lubricating drops that will alleviate the scratchiness and dryness. The wonderful thing about artificial tears is you can use them as often as you like and they are easy to carry. If for some reason artificial tears do not work for you, then you probably need something stronger like Restasis drops. These drops help more than artificial tears because they actually stimulate your eye to produce more tears. When your eye has more tears you have less scratchiness and dryness.

If your dry eye problem is caused by the environment then there are several precautions you can take. First, use a humidifier indoors if the air is drying your eyes out and always wear sunglasses outside to reduce sunlight and debris.

If your dry eye problem still persists, you might need plugs to reduce your tears evaporating so quickly or eye duct surgery. Some optometrists have also found there are supplements available that contain fatty acids that protect against dry eyes.

Regardless of why you have dry eyes, talk with your optometrist to make sure you are handling the dry eye situation as best as possible.

Who Invented the Contact Lens?

Many believe the contact lens is a relatively new invention and was conceived in this century due to technology and innovation. While the contacts of today were developed not so long ago, its inception and inspiration began many centuries ago.

This probably comes as quite a shock to many; however the idea of contact lenses began with Leonardo da Vinci. In the 16th century Leonardo da Vinci made sketches of a variety of possibilities and included descriptions of them. Then, more than 100 years later Rene Descartes developed the idea of a corneal lens that would correct visual problems. Thomas Young used Descartes idea 170 years later and developed what has been considered the first lens. However, it would be in 1887 that a German glassblower would develop a contact lens that was designed to be worn and accepted by the eye. After this, the whole world began the quest to develop and improve the designs.

In the 1900s an American optometrist produced the first lens in this country and introduced the contact lens to plastic. This was a huge step and was a move away from glass contacts. The contact industry and technology continued to expand and grow and by the 1960s Otto Wichterle and Drahoslav Lim created a soft contact lens of a water absorbing plastic. This development is what most inspired the majority of soft contacts today. The 1970s found this lens available to patients in the United States as well as the toric contact lens for patients with astigmatism.

The 1980s continued to see improvements and new options in contact wear. Soft colored contacts as well as extended wear lenses became available to the general public. Also, RGP lenses became available in these styles as well. Bifocal lenses also made their way onto the market. And fortunately for all lens wearers, the first multipurpose lens care solution became available. The 1990s continued to see an improvement on all the innovations from the '80s and more options became available for contact lens wearers.

As you can see, there was no one inventor of the contact lens, but rather collaboration over many centuries and many individuals developing new ideas and implementing them.

Non Prescription Contact Lenses Are the Best Way to Alter Your Look Without Altering Your Sight

Today's world has a staggering 75 million contact lens wearers, with 31 million living within the United States. Though it might seem as though this is an awfully large number of people who opt not to wear glasses, there are actually quite a few people who are wearing non prescription contact lenses to alter their look, but not their vision. Non prescription contact lenses are a unique way to change your appearance by way of your eye color, whether making a dramatic change, or a slight enhancement.

As long as you first visit an optometrist, you'll know the correct size so that you can find the contact lens that it best suited to your eye. After a brief period of initial adjustment, most people discover that they can't even feel their non prescription contact lenses anymore.

There are a number of different kinds of non-prescription colored contacts out there. Opaque coloured lenses are able to transform even the darkest natural eye color into a brighter or lighter shade. These lenses are clear in the center so that the wearer can see through the pupil, but the colorless part is surrounded by a wall of color. This allows for the most dramatic change even on the darkest background.

For those who have lighter eyes, enhancement lenses are usually the more natural option. These are still available as non prescription coloured contacts, but instead of being completely opaque, they augment the wearer's natural eye tint with more subtle and flattering hues.

For people who have a wilder streak about them, then there's a broad range of non-prescription novelty contact lenses that are currently all the rage. You can now look like an alien, as though you have cat's eyes, flaming eyes, or any other possible appearance that you could ever want. Essentially, if you want it, they have it.

Surprisingly enough, changing the look of your eye isn't the only reason that non prescription contact lenses exist. Many hospitals and clinics will utilize a special type of clear lens as a sort of bandage for the cornea, especially after the patient has undergone surgery for a cateract. Also, sports players and fanatic spectators will choose to use contact lenses that include filters for certain lights and colors so that they can better see the ball or whatever other target they may need to see.

No matter the reason that you choose to buy non prescription contact lenses, they're certain to be comfortable and satisfying for you. Take advantage of a free offer from your favorite brand, and give them a "test drive", so that you know that you can use them comfortably and without irritation.

Does Laser Vision Correction Really Work?

Have you considered laser vision correction, but are scared it won't work out and you will be back to where you started from only with less money? If you are considering LASIK eye surgery then do not be afraid or concerned that it does not work. There a millions of cases of laser vision correction surgery that has met or exceeded the patients' expectations. There are a few situations where the surgery fails, however this is in the minority and can frequently be fixed in a follow up surgery.

There are many reasons why laser vision correction is a great option for individuals who need and want good vision without glasses or contact lenses. However, sometimes the correction does not go far enough and the patient is left still wearing glasses or lenses.

Laser correction works because the cornea is reshaped so the eye can process light correctly and reduce fuzziness while improving clarity. The cornea is reshaped by a laser and because of this sometimes the surgery can remove too much slope or not enough. When this happens the patient is in need of a follow up surgery or is relegated to wearing lenses or glasses. However, this does not happen frequently and patients generally get near to perfect or perfect vision with this procedure. As a result, this surgery really does work and allows patients clear and improved vision in most cases.

If you are still concerned about laser vision correction and want to know if it is right for you, visit an ophthalmologist for a consultation. This should help allay your fears and help you realize that laser vision correction is a wonderful option and more often than not is hugely successful. If you are still skeptical, talk to some people who have previously undergone the procedure. This first hand recount will help you know if laser vision correction is for you.

Changing Opinions on RGP Contact Lenses

Rigid gas permeable contact lenses, also known as RGP lenses, have made quite a few strides over the past decade and can provide comfort and improved vision to the wearer. However, many people have a negative opinion associated with these lenses. Fortunately, these lenses have changed for the better and are on a comeback.

Rigid gas permeable lenses actually have quite a few bonuses that soft contact lenses cannot provide. For instance, RGP lenses provide the wearer with increased eye health because these contacts can breathe and circulate oxygen to the eye. RGP contact lenses have many positives and they just might change your opinion regarding these lenses.

RGP lenses are more durable and resistant to protein buildup than their softer counterparts. This leads to easier handling and clearer vision because buildup does not occur so easily. Also, these contacts generally provide clearer and crisper vision, anyway, because they are more rigid. RGP contacts are more durable and so they generally last longer because they are not so fragile. This is good for the RGP contact wearer because these contacts are a little pricier than soft lenses. However, they are generally cheaper over the long haul because they last so much longer if taken care of.

Another great trait of rigid gas permeable lenses is because of their durability they can be marked with L and R to denote which eye the lens is for. This certainly eliminates any confusion.

The biggest negative associated with RGP lenses these days is it takes longer for the eye to accept them and be accustomed to wearing them. This is opposed to soft lenses which generally just takes a few days. These lenses must also be worn on a regular basis so as not to go through the process of re-aclimating the eye to the lens.

If you had a negative opinion of RGP lenses in the past this information should show you that RGP lenses have come a long way and are certainly a viable contact lens option.

How Do Contact Lenses Work?

Contact lenses rest on your cornea atop a constant supply of tears. The contacts are also held in place by pressure exerted from the eyelids. When you blink the pressure from the eyelids cause the contacts to move slightly and glide over your cornea. This allows the tears underneath to gently flush out trash or debris that may have accumulated in your eye.

This is just how the contact stays on the eye and is able to provide a way to correct vision. The way the vision is corrected is a different story altogether.

Contact lenses are prescribed to a wide variety of individuals who have vision problems associated with astigmatism, nearsightedness, farsightedness, and presbyopia. The retinas of individuals who suffer from these conditions cannot properly focus light. When the retina does not function properly and/or does not properly focus light then the result is imperfect and blurry vision.

Contact lenses are made differently depending on the eye condition they are trying to correct. For instance, if you suffer from astigmatism your optometrist will measure your cornea so a contact can be made precisely to fit your eye. By doing this a contact is made that will fit your eye perfectly and direct light rays to one place on the cornea, which in turn corrects your vision.

Those suffering from myopia, also known as nearsightedness, will wear lenses that are thinner in the middle and thicker on the edges. This design allows the light rays to be processed correctly by the retina.

Farsightedness sufferers are prescribed just the opposite contact lens, but with the same end result. They allow the retina to process light correctly as well, resulting in corrected vision for the wearer.

All contact lenses use the basic technology to correct vision for the wearer. They redirect light to the retina so it is processed correctly. The only difference is contacts are made differently to treat different eye problems.

Can Astigmatism Be Cured?

Astigmatism occurs in individuals who have a cornea shaped like a football. The cornea should be shaped like a baseball in order to reflect light correctly. When it is shaped like a football there is more than one curve on the cornea, generally a steep one and a flat one. This causes light to reflect on more than one point in the retina which results in blurry vision for the patient. Frequently nearsightedness or farsightedness occur with astigmatism.

There is not necessarily a cure for astigmatism. However, there are a variety of ways to correct astigmatism that include surgery, glasses or contacts.

Surgeries used to correct astigmatism most frequently are astigmatic keratotomy and LASIK. Astigmatic keratotomy is performed by cutting a microscopic incision in the eye and reshaping the cornea. LASIK is performed by cutting a small flap in the eye and then reshaping the cornea through lasers. Although these procedures are performed somewhat differently, they are used to reshape the cornea and provide clearer vision. The object of the surgery is to make the cornea more spherical like a basketball instead of shaped like a football.

Glasses correct astigmatism by redirecting the light to the retina. This produces clearer vision for the astigmatism sufferer. Contacts work in a similar way also and are used to redirect the light. Many years ago there were only rigid gas permeable contacts available for astigmatism sufferers, but times have changed and today there are soft lenses available as well. Depending on your eye prescription and how much astigmatism you have, will affect the correction options available to you. If you suspect you have astigmatism, or know you do, talk to your optometrist about the variety of correction options and the ones that would be most effective for your vision and lifestyle.

Is LASIK Right For Me?

The subject of LASIK is a very interesting one. There is a lot to investigate and understand about the process of getting your vision corrected through laser surgery. I hope this article helps to point you where you need to go to do the best research. There are both pros and cons to consider before submitting to this type of surgery.

First, if you are already firmly set in your decision to have LASIK, read these pointers:

1. Make sure you go to a doctor who uses the new Interlase laser for making the corneal flap.

Why? Because the Interlase is 100 times more precise than the "old fashioned" method of using a microkeratome to cut the initial flap. Many speculate that most of the problems that come from LASIK surgery have been due to the impreciseness of the microkeratome device used to cut the cornea.

2. Most definitely insist on a custom wavefront laser to do the actual reshaping of the cornea.

Why? Because the custom wavefront can get rid of what is called higher order aberrations.

What does this mean to you? It means much sharper vision after the surgery and a significantly reduced chance of having halos, starburst and other "complications" from LASIK.

Repeating: Make sure you go to a surgeon who is using both Interlase and Custom Wavefront technology to do LASIK surgery. Relatively few practices have these new technologies. Consider that surgeons who invest in these technologies may have more of your interests at heart.

One of the top 5 LASIK surgeons lives in Kansas City. Check out his site: durrievision Look at the information on his site including the videos where he explains what LASIK is all about. Compare your perspective surgeons website to his and you may detect a difference.

Next, you should be aware of the potential problems of LASIK surgery as you review surgical eyes - you may find that these horror stories came from procedures that didn't use interlase and custom wavefront technology together. See-there is a reason to go with the newer technologies. You can email the people on this site and ask them questions about their procedures and the complications that they faced or are still facing.

One of the problems with LASIK, has been the LASIK 20/20 phenomenon. Some people do technically see 20/20 after the procedure but it is not normal. Instead, it is hazy or blurred. This is probably due to the higher order aberrations mentioned earlier. That is why it is important to get custom LASIK done. The custom wave front lasers can remove those aberrations, hopefully allowing you avoid the LASIK 20/20 phenomenon.

If your doctor says that you don't need the custom treatment, I would ask him if he has a custom wave front machine. There may be a few legitimate reasons to not have the custom procedure done, but I seriously doubt there are many.

If he doesn't have such a machine, I would wonder if his recommendation is based on the best thing for you as the patient. It always pays to get a second opinion anyway and in this case, you should.

These are your eyes that we are talking about and you owe it to yourself to get educated on every aspect of this surgery before undergoing treatment. The surgical eyes web site mentioned above is worth investigating. You need to know what could go wrong and how to choose a doctor and equipment that will allow you to avoid problems.

I will say it again. Try to go with Interlase to cut the corneal flap and try to go with a custom wavefront laser to reduce your risk of complications! I cannot stress this enough.

I went through a screening process to get LASIK done and was categorized as an excellent candidate. They even wanted me to participate in a study program that would save me about $600. I still turned it down. In the end, I decided that I didn't want to get my eyes lasered.

Of course, there is something to be said about not wearing glasses or contacts anymore and there are many happy patients out there. I just want you to be aware of both the pros and the cons.

Do you really need to have LASIK done? I think its worth it to investigate natural vision therapy and see what you can do about correcting your vision naturally before permanently etching your current prescription into your cornea.

Many people have gotten results from vision therapy. A few have even gotten rid of their glasses and /or contacts forever. An industry insider has informed me that this does happen but not very often.

There are a couple of books to check out on natural vision improvement if you are interested in that alternative. Relearning to See by Thomas Quakenbush is one that comes to mind.

The original pioneer in vision improvement was Dr. Bates. He was an early 20th century ophthalmologist who really stuck his neck out to go against the prevailing theories of the day (that still persist). Many of the people who he helped were very grateful, Im sure.

I have dabbled with naturally improving my vision. I have experienced a decrease of tension, but I have not recovered 20/20 vision. This type of improvement does take work and determination.

That is why there is LASIK today; everyone is different in their wishes and expectations. If you are in a hurry and you don't mind the permanent etching of a prescription in your cornea, LASIK might be for you.

I hope this helps you on your quest to learn more about LASIK Surgery and point you in the right directions to gain more information so that you can make an informed decision before deciding to undergo this often expensive elective procedure. Below the disclaimer you will find a link to additional information.

For Dry Eyes Use An Approved Eye Drop

Cyclosporine eye drops may make artificial tears unnecessary. That's because the treatment helps your eyes to make their own tears if you use it on a regular basis. The FDA approved the use of Restasis, the brand name for the generic drug Cyclosporine, in 2002 as a treatment for chronic dry eyes.

How Do You Know if You Have Dry Eye?

Your eyes will tell you if you have the problem. You might find tears running down the sides of your cheeks and your eyes burning or stinging. While it doesn't seem to make sense that eyes that are dry can cause tears, it's just the body's reaction to the dryness. Tears are more than just saline water. They contain oil that acts as a lubricant and method of maintaining moisture. The tears also contain antibodies, special proteins and mucus. The mucus allows the tears to spread evenly across the eye. If any part of the system is out of balance, you might experience the problem.

At first, you might think you have a foreign object in your eye such a piece of sand or dirt. Your lid feels scratchy to your eyeball when you close it. Your eyes might be sensitive to light or feel bulging with pain. You'll normally experience a lot of eye redness. Sometimes, it is so bad that your vision blurs. Even though you have tears flowing freely, the tears fail to adequately coat the eyeball because there's an element missing or an imbalance in the tear's composition.

What Causes Dry Eye?

Poor tear quality, tears that lack water, oil and mucous in the right amounts, are not the only cause of the problem. Dry eye comes from the body's ability to produce enough tears, too. Sometimes, that condition comes from simply growing old. It tends to occur in women past menopause or people over 50. Medical conditions such as lupus, thyroid disorders or rheumatoid arthritis also cause lack of tears. Laser surgery, tear gland damage and eyelid problems that don't allow you to blink as often, which spread the tears, also cause dry eye. You might develop the problem if you're taking certain medications such as antihistamines or decongestants. Blood pressure medications that act as diuretics and birth control pills cause dry eye too.

Pain relievers such as ibuprofen, antidepressants and isotretinoin, an acne treatment also cause drying of the eyes. One attack doesn't mean you necessary have a drug reaction or physical problem, it could mean it's a windy day, you're at a high altitude, the air's dry or you've been concentrating so hard that you forgot to blink.

Cures for Dry Eye

Complications seldom occur from the problem but when they do they include frequent eye infections and scarring on the eye surface. However, if you experience the discomfort and pain of dry eye, you'll want to do something about the problem. You have a choice of using artificial tears, plugging the tear ducts that drain the tears either permanently or temporarily, topical steroids, ointments, Cyclosporine or surgery. In many cases, the use of Cyclosporine eye drops for dry eyes helps your eyes make their own tears so other treatments are often unnecessary.

How to Maintain and Clean Your Contact Lenses

The popularity of contact lenses over eye glasses continue to grow at a remarkable rate. In fact, 25 million people worldwide wear contact lenses. It does not take a lot to see the benefits of lenses, including enhanced function and comfort. If you're interested in contact lenses, it's vital that you understand the method and practices to maintain them properly.

A contact lens is a Food and Drug Administration (FDA)-approved medical device that can only be prescribed to you by an eye care practitioner. Lenses should never be purchased in beauty supply stores, salons, or flea markets. When you choose contact lenses, it is important to keep a back-up pair of glasses readily available in the case of irritants that may arise, including seasonal allergies, sinus pressure, or a cold.

How to Find the Right Fit

After speaking to a doctor about whether or not contact lenses are right for you, he or she will begin the examination process in order to fit you for the right lenses. The doctor will take measurements of your corneal curvature in order to determine which lens would fit without being too tight or too loose. If a contact lens fits over the cornea too tightly, it could cut off the oxygen to the eye leading to swelling or blurred vision. This process is intricate, yet important to maintaining your eye health.

Once you have been prescribed the right contact lenses, it's important to understand the importance of proper maintenance. To avoid any disruption in your vision, which can include everything from a minor irritation to an eye infection, you have to regularly cleanse and dispose of your contacts when required.

Disposable contact lenses should generally be replaced on an every day, every two weeks, or every month time line. Read through the details of your prescription so you know when they should be replaced and comply with those regulations in order to avoid any type of eye injury. Some people will use the prescription directions as more of an estimate. As a result, they will wear contact lenses as long as they feel moderately comfortable then replace them when they start to feel "old." This practice is the fastest way to create an environment of bacteria, protein, and debris build up.

When you leave your contacts in for longer than the recommended replacement time, the lens will accumulate a buildup of bacteria that causes the cornea to become inflamed. The inflammation can lead to redness, tearing, light sensitivity, and pain. If the problem progresses, white blood cells will accumulate and cause a white spot on the cornea that could become visible on the eye. If left untreated, the spot may form into a permanent scar, which will affect the vision. More importantly, a bacterial infection in the eye can cause an ulcer on the cornea, which is both painful and often permanent.

When you rinse or clean your contact lenses, avoid tap water or reused solution. This cleansing practice can lead to a fungal infection that may be hard to treat and lead to a corneal transplant. Also, avoid sleeping in contact lenses as it can lead to an infection as well. When your eyes are closed, oxygen is cut off from the eye thus your lenses will dry overnight. If you'd like the option of being able to sleep in your contact lenses, ask your doctor about "highly breathable" lenses.

When the proper hygiene practices are in place, contact lenses can be comfortable, easy to wear, and safe. If you have any questions or would like to learn more tips about cleaning and maintaining your lenses, contact your eye care professional today.

What is Low Tension Glaucoma?

What is low tension glaucoma and what is the difference to other types of glaucoma? Low tension glaucoma is a chronic medical condition in which an insufficient amount of blood supply reaches the blood vessels supplying the optic nerve located at the back of the eye.

When not enough blood is flowing through the small artery located at the back of the eye to feed the many smaller arteries, the optic nerve becomes damaged and the result is a reduction in sight.

The term low tension glaucoma refers to the fact that the pressure supplying blood flow to this area of the eye is too low and creates vision problems. Regular glaucoma, by comparision, is a condition in which high pressure within the eye stops the blood from entering the optic nerve arteries and blood vessels, also causing a reduction in sight and in severe cases, blindness.

Cause of Low Tension Glaucoma

The cause behind the low pressure that results in low tension glaucoma has not yet been pinpointed, but in most cases, the optic nerve is never damaged badly enough to cause blindness. Most patients with this condition respond well to eye drops prescribed by their eye doctor.

Low Tension Glaucoma Treatment

Eye drops work to relieve this condition by creating less fluid in the eye, which in turn helps to bump up the volume of pressure needed to get blood adequately flowing into the optic nerve artery and blood vessels. Some eye drops work by draining fluid from the eye, creating the same effect of boosting the pressure needed to get an increased blood flow to the optic nerve at the back of the eye.

If a patient does not respond to eye drops, an operation is another alternative. A small incision is made in the eyeball to drain some fluid from the eye in order to increase the pressure for distributing blood flow to the optic nerve. Called a trabeculectomy, it is an operation that must be performed by an experienced opthlalmic surgeon.

No matter what treatment option is pursued, early detection of low pressure glaucoma is the best preventative against an increasing loss of vision in the future. Another very effective method is treating glaucoma naturally, using eye targeted exercises and learning how to completely relax the eyes.

Symptoms and Treatment of Glaucoma in Adults

What is Glaucoma? What are the Symptoms of Glaucoma in Adults and What Can You do About it?
Glaucoma is a scary thing because by the time the first symptoms in adults show up it is too late to do anything about it. It is a condition that gets progressively more common as you get older.
About 2% of today's adult population over the age of 40 have glaucoma and it is more common among people who already have someone with glaucoma in their family.
This lens will take a look at the causes, the symptoms and treatment options for glaucoma in adults.

Causes and Symptoms of Glaucoma in Adults

The main causes of Glaucoma are poor circulation around the eyes, plugged channels, and poor drainage. These are the consequence of too much stress, strain, outside stressors, and too many toxins in the body.

The first symptoms of Glaucoma are tunnel vision and the narrowing in the field of vision. This quickly moves into the final stages of Glaucoma which is permanent blindness

Short Video That Shows How Glaucoma Develops




Traditional Glaucoma Treatments Usually Fail

The only treatment options for Glaucoma are to give medication for the tension or to drain the fluid from the eyes.

These are both quick fixes and they only work to relive the symptoms, not the problem. Most people will still end up with blindness. These fixes just prolong the inevitable for awhile longer.

As mentioned Glaucoma is usually caused by stress and once diagnosed with the disease the stress doesn't stop but only becomes worse. Now people are anxious and nervous and scared of the blindness. Fear of the unknown and worry starts to consume their daily life, only adding to the stress and strain on the eyes. In the end, they are only making the symptoms worse instead of taking steps to try and fix the issue.

What You can Really Do...
Learn How to Relax Your Eyes

Anyone who suffers from Glaucoma should seek medical attention because if left undetected permanent blindness will happen.

However, you can take steps to treat glaucoma naturally yourself by learning to relax the eyes. Take the time each night to fully relax before going to sleep. While lying in bed with your eyes closed, picture your muscles relaxing from your head down to your toes. Concentrate especially on relaxing those muscles around the eyes. Fully relaxing before falling asleep will ensure a better night's sleep and waking up refreshed.

Low Tension Glaucoma and Blindness - How Serious Is Low Pressure Glaucoma?

Although it doesn't necessarily lead to blindness, low tension glaucoma is a serious illness and should not be disregarded. When suffering from this particular type of glaucoma, an insufficient volume of blood gets to the capillaries supporting the optic nerve at the rear of the eye, which very often causes diminished eye-sight.

The expression low tension glaucoma relates to the fact that the stress delivering blood flow to this area of the eye is too low and therefore creates vision problems. When not enough blood is going via the compact artery found at the back of the eye that will feed the various smaller arteries, the optic nerve will become damaged and the outcome is a decrease in sight. Typical glaucoma, by comparison, is a dysfunction in which increased pressure inside the eye stops the blood flow from getting into the eye nerve arteries and blood vessels, also producing a decrease in sight and in serious occasions, blindness.

The reason behind the low tension that results in this type of glaucoma hasn't yet been determined, but in many instances, the optic nerve is not destroyed critically enough to lead to blindness. Most people with this problem react fine to eye drops given by the physicians.

Eye drops succeed to relieve this condition through producing less fluid inside the eye, which in turn helps to boost the amount of pressure needed to get blood thoroughly flowing into the eye nerve artery and veins. Some eye drops operate by draining liquid from the eye, creating the equivalent effect of elevating the pressure needed to have an increased the circulation of blood to the optic nerve at the back of the eye.

In case a sufferer will not improve with eye drops, an operation is another alternative. A little incision is made in the eyeball to drain a little liquid from the eye as a way to boost the pressure and send the flow of blood towards the optic nerve. Referred to as a trabeculectomy, it is definitely an operation that has to be carried out by an experienced opthlalmic surgeon. Regardless of what treatment choice is pursued, early recognition of low pressure glaucoma is the ideal preventative from an increasing loss in vision

All the same, individuals are in a position to take action themselves towards treating glaucoma naturally by doing targeted eye exercises and figuring out how to totally relax their eyes.

Eye Exercise to Improve Eyesight

Eye tracking problems do have a lot to do with eyesight. Tracking means following incoming information and processing or working on it in your brain to get the correct meaning of the information. Inability to concentrate on letters and numbers and comply on the page can spoil your ability to learn and understand. Out of all learning, seventy percent of them come through the ability to track with our eyes. Eye tracking is divided into three main abilities: regression or fixation, saccades and pursuit.

The comforting news is that eye-tracking problems can be improved by doing simple eye exercises. Below are eye exercises to improve your eyesight without glasses.

One of the main poor vision problems people may have is fixation, which is an inability to keep eyes settled on an object. This problem commonly goes along with minimal brain dysfunction, which results in difficulty with concentrating or concentrating on one thing at a time. The best and easiest way to test for this problem and also to get rid of it is to do this exercise: Hold two different looking pens (for instance; one green and one yellow), it should sixteen inches apart from your face. You should look at the green pen and after a second look at the yellow one. Keep changing or switching back and forth between pens, but change the number of times in between each switch.

Improving your eye's saccade tracking ability, which is the ability of the eyes to jump from one object to another, can be handled with flashlight games or flashlight tag. In a room that is dark, either lie on the floor or sit on the bed with someone beside you. Let your mother, father and yourself hold a flashlight. You can take turns in which one of you shines the light on an object and the other shines their light on the same object as fast as possible. You can also follow the leader with the flashlights, which will help to improve the pursuit function of eye tracking. In this game, one person shines the light, tardily dragging it along the wall and ceiling, and the other pursues it with their light.

Another eyesight enhancing exercise that contains all the three eye-tracking skills involves hanging a small plastic ball from the ceiling. You need to hit the ball with a plastic bat repeatedly. As you improve on this game, switch to a small paper towel roll for a bat. You need to concentrate on the ball, track it as it moves and follow it with the bat on each subsequent hit. These are the easiest ways to enhance your vision.

Blade vs. Bladeless LASIK - What You Need to Know

Vision correction surgery is the answer for millions of men and women who rely on glasses or contacts to see clearly, and LASIK technology has become increasingly accurate and precise in recent years so patients can enjoy a safe and effective treatment. However, many surgeons perform laser eye surgery using either a blade to cut the corneal flap, or a laser called IntraLase to perform ‘bladeless’ surgery. 

The November 2007 issue of the Journal of Refractive Surgery took a close look at the outcome of LASIK surgery with both the bladeless procedure and the conventional blade. Researchers found that the people who had undergone the LASIK procedure with IntraLase experienced better visual outcomes in both the short and long-term. Visual quality was much better for those who opted for the bladeless technique, but it is not without its risks.

Which type of surgery really offers the most benefits? Here’s what to consider when researching blade or bladeless LASIK for your vision correction procedure:

Pros and Cons of Blade LASIK

The traditional LASIK procedure continues to be a popular treatment option for individuals who want near-perfect vision, but using a blade to cut into the cornea does present some risks. While a skilled surgeon can complete the procedure with minimal or no side effects, the risk of visual distortions is still relatively high. The blade used in LASIK is used to create a very precise corneal flap, but some surgeons may not be able to cut into the cornea accurately enough; the common complication of blade LASIK is the ‘buttonhole flap’ which leads to several vision problems.

Pros and Cons of Bladeless LASIK

Bladeless LASIK has been proven safe and effective because flap complications are rare. Some refractive eye surgeons suggest that flap predictability is simply better using a laser flap. Since the laser can be tracked on the cornea more precisely, the incision can be made with fewer complications. However, bladeless LASIK still presents some risk. 

Some patients report light sensitivity after their LASIK procedure with IntraLase, and this cannot be corrected in any way. Another drawback of bladeless LASIK is the cost; IntraLase is significantly more expensive than traditional LASIK, and doctors may charge extra fees for this specialty service.

Ongoing studies continue to point out that both blade and bladeless LASIK are equally as effective at correcting vision problems, but the outcomes largely depend on the surgeon’s experience and skill level, as well as the patient’s overall health and condition. Making sure that the eyes are dilated during the consultation and the surgeon has a chance to complete all pre-surgery assessments is a very important element of the procedure.

Finding an experienced and well-trained surgeon is another important factor when pursuing laser eye surgery. A skilled surgeon with several years of experience using the traditional blade procedure may provide a much better outcome than someone who has recently started using the IntraLase system.

Benefits and Drawbacks of the iLASIK Procedure

Millions of men and women pursue laser eye surgery to achieve near-perfect vision without glasses or contacts, and there are now several innovative vision correction treatment options available. iLASIK is one of the latest procedures designed to reshape the cornea within a matter of minutes. Instead of undergoing extensive surgery, this quick and simple procedure can be done under 10 minutes and is designed to be almost painless. iLASIK also promises 20/20 vision or better one year after treatment. 

 

Does iLASIK sound good to be true? Here’s what you need to know.

 

How the iLASIK Procedure Is Performed

iLASIK is performed using computer software that creates a blueprint of your eyes. This digital blueprint offers a more precise and accurate result, according to iLASIK.com, and helps the surgeon guide the laser to exactly the right area of the eyes. 

 

The first laser used on the iLASIK procedure is used to make a thin flap in the cornea, and the second laser makes the correction based on the blueprints. All patients receive numbing drops before the procedure so they rarely feel any pain, and the entire process takes less than ten minutes per eye, in most cases.

 

Conventional LASIK procedures require the surgeon to use a thin blade to cut into the cornea, but this presents several risks and the cut may not be made in exactly the right place. The iLASIK procedure makes use of the IntraLase laser which cuts into the cornea more precisely. 

 

Key Benefits of the iLASIK Procedure

The iLASIK procedure is one of the most convenient and affordable vision correction procedures available, and offers several benefits including:

• High accuracy rate 
• Safe and proven technology
• Virtually painless
• Likely to achieve 20/20 vision or better after surgery
• Average costs range between $2,000 - $3,000 per eye
• Financing available directly from the iLASIK surgeon

Drawbacks of the iLASIK Procedure

While the iLASIK procedure offers several benefits, there are some drawbacks to this innovative vision correction treatment.

The iLASIK procedure is relatively new and long-term studies have not been conducted to determine the effectiveness of the procedure after several years. 

 

Prospective patients who are under 21 years of age cannot have the iLASIK procedure, and anyone without a stable vision prescription for at least one year will also need to wait for iLASIK; the procedure can only be performed on eyes that are not changing.

 

Finally, the iLASIK procedure may not be available in your area which means you may need to travel extensively to find a surgeon. However, more doctors are being trained for iLASIK as the procedure becomes more popular around the country.

 

The iLASIK procedure has been proven to be safe, but is not without complications and some risks. Learn more about laser eye surgery treatment options in our information guide, or consult with a laser eye surgeon to find out if you are a good candidate for iLASIK or other vision correction procedures.

Guide to Advanced IntraLase Femtosecond Laser (iFS) Bladeless LASIK

LASIK laser eye surgery continues to be a popular choice for vision correction. Bladeless LASIK is one of the latest advances in the field, and many LASIK doctors are now offering the Advanced IntraLase Femtosecond Laser (iFS), a very precise and targeted laser that can create a small flap needed for LASIK correction and other laser eye surgery procedures. The iFS bladeless LASIK device offers a number of advantages over other procedures, and is not currently available at all LASIK vision correction centers.

If you are interested in learning more about iFS bladeless LASIK, set up a consultation with a LASIK specialist in your area. Your LASIK doctor can perform a thorough eye evaluation and determine whether you would be a good candidate for iFS bladeless LASIK or another bladeless LASIK procedure.

Benefits of Bladeless LASIK

Bladeless LASIK, also known as IntraLASIK, offers an alternative option in vision correction for people who fear the hand-held blade used in traditional LASIK procedures. Some doctors simply prefer bladeless LASIK over other procedures because it may be safer and the level of precision is higher than other procedures. Some of the top benefits of bladeless LASIK include:

• Reduced risk of corneal flap complications
• Precise and accurate vision correction
• Reduced risk of dry eye after the procedure
• Track record of positive results

How Advanced IntraLase Femtosecond Laser (iFS) Bladeless LASIK Works

The iFS bladelessLASIK laser has raised the standard of LASIK flap creation in refractive surgery because it gives the LASIK doctor more control and works at a very high speed. The flaps can be customized for the individual cornea, and the lower energy output means there is less risk of tissue damage or inflammation to the cornea. The LASIK surgeon can use a video microscope to magnify the treated area, and the machine itself is designed to complement and enhance the iLASIK patient experience.

People who have already had LASIK laser eye surgery and had some problems with the flap creation process may be good candidates for the iFS bladeless LASIK procedure. During the procedure, the laser moves back and forth across the surface of the eye to create a very small layer of bubbles just below the surface of the cornea. A series of light pulses are emitted through the top layers of the cornea at various lengths. The flap is gently folded back over the cornea and the vision correction portion of the procedure is performed.

The entire iFS bladeless LASIK procedure is relatively comfortable and most patients experience little to no complications. One of the most common side effects of the bladeless LASIK procedure is light sensitivity, but this typically subsides within a few days.

Guide to the MultiFocal LASIK Procedure

LASIK laser eye surgery and bladeless LASIK continue to be among the top choices for patients interested in vision correction, but a new LASIK procedure may offer even better results. The MultiFocal LASIK procedure, also known as Bifocal LASIK, presbyLASIK and Presbyopic LASIK is designed for people who commonly use bifocals to improve their vision. This new LASIK procedure was recently featured on The Doctors TV show and offers a number of benefits for patients who want to say goodbye to their bifocal lenses for good.

If you think you may be a good candidate for the new MultiFocal LASIK procedure, set up a consultation with a LASIK doctor in your area. Your doctor will explain what the benefits and drawbacks of the MultiFocal LASIK procedure are, and what you can expect from this innovative type of laser eye surgery.

Top Benefits of MultiFocal LASIK or presbyLASIK

MultiFocal LASIK or presbyLASIK offers a number of benefits and early studies have shown very promising results. Some studies suggest that MultiFocal LASIK offers the following benefits:

• Improve vision for far-sighted patients
• Allow some patients to become completely free of eyeglasses within two years of surgery
• Has a low risk of reduced contrast sensitivity, a common problem in patients who undergo other types of vision correction treatments
• Patient can still undergo cataract surgery after LASIK if needed

Even though MultiFocal LASIK has several advantages, there is no guarantee of results and the eyes may change as the years go by. Some complications can occur with this procedure, but most people find that the benefits do outweigh the risks.

How MultiFocal LASIK Works

Unlike regular LASIK and bladeless LASIK procedures, MultiFocal LASIK creates more than one power on the surface of the cornea so that you can see more clearly through different zones on the eye. MultiFocal LASIK makes it possible to see clearly over several distances, instead of just one distance. The laser reshapes the clear surface of the eye just enough to alter the way light enters the eye. Conventional LASIK procedures can only correct eithernearsightedness or farsightedness.

The MultiFocal LASIK procedure corrects presbyopia by reshaping the cornea into different zones for near, far and intermediate vision correction. Your brain will adjust your vision accordingly to create the sharpest picture. The light is refracted differently in each zone, so you can regain vision at all distances, instead of just one distance.

This type of LASIK procedure is customizable so the chances of improving vision without errors is reduced when compared to conventional procedures. Many LASIK doctors are still experimenting with different techniques to design the most effective approach. In most cases, MultiFocal LASIK cannot be reversed.

Learn more about the latest LASIK procedures in our information guide, or set up a consultation with a LASIK surgeon in your area. The MultiFocal LASIK procedure is still undergoing clinical trials, as of January 2011, but may soon be available at many laser vision correction centers around the United States.

The Excimer Laser

Doctors have been routinely treating nearsightedness, farsightedness and astigmatism with incisions for over 25 years. By the early 1980s, they began looking at lasers to improve the precision and predictability of altering the shape of the cornea. Researchers found that IBM's new Excimer laser, used initially for etching computer chips, had medical applications as well. Now in its second decade of use, the technologically-advanced Excimer laser has added a tremendous amount of precision, control and safety to treating nearsightedness, farsightedness and astigmatism.

Its ability to remove corneal tissue with accuracy up to 0.25 microns (0.00004 of an inch) with each pulse makes the Excimer laser well suited for correcting vision. Often, only 50 microns of tissue (about the thickness of a human hair) are removed to achieve the proper amount of correction.

The Excimer laser produces a "cool" or non-thermal light beam as most of its heat is dissipated into the air. This makes it ideal for corneal surgery because it eliminates the possibility of thermal damage to surrounding tissue.

Excimer Laser Procedures (LASIK, PRK, PARK)

Photo-Refractive KERATECTOMY (PRK)
uses the excimer laser to correct low to moderate amounts of refractive errors. PRK treats nearsightedness by removing corneal tissue from the surface of the cornea, causing the central optical zone to flatten. This allows light rays to focus more directly on the retina, thereby reducing nearsightedness. The amount of tissue to be removed is determined by the amount of nearsightedness to be corrected. For most patients, only five to ten percent of the cornea is removed to obtain the desired results.

Photo-Astigmatic Refractive KERATECTOMY (PARK) can be used to treat low to moderate amounts of astigmatism. Since regular astigmatism is caused by the cornea being steeper in one direction, like a football, the excimer laser beam is shaped to remove more tissue in one direction than the other. The result is a more spherical cornea that allows light to focus more directly on the retina. PARK can usually be done in the same session as PRK or LASIK.

LASIK is an acronym for LASer In-situ Keratomileusis, which simply means "to shape the corena within using a laser." It corrects vision by reshaping the cornea (outer window of the eye) so that light rays focus more precisely on the retina, thereby reducing or eliminating refractive errors.
