Should You Wear Contact Lenses Instead of Glasses?

Monday, June 29th, 2009

Are you tired and annoyed with wearing eyeglasses? Are you thinking about maybe switching to wearing contacts instead? Wearing contact lenses probably isn’t as difficult as you may think and there are a number of advantages as well. Find out more by taking a minute to read this short article about wearing contact lenses.

A Little History

Early contact lenses amazingly date back into the 19th century. At that time, they were made of brown glass and were not easy to wear. They were, however, helpful to people that could not wear eyeglasses. Contact lens technology improved in the 1940s and 1950 when they were able to make them from plastic instead. These were made out of a plastic material called polymethyl methacrylte and worked well. The only problem was that they did not allow oxygen to easily pass through them. Since then, the plastic material has improved and is now rigid gas permeable, allowing oxygen to get to your corneas. This is necessary because your corneas get the oxygen they need from the air, not your bloodstream.

Even in the last few years there have been an increase in technology in contact lenses as lenses are now being made for people with astigmatism and even for people who need bifocal lenses.

Why is it Good to Wear Contact Lenses?

People wear contact lenses for cosmetic advantages as well as:

* Unlike glasses, the lens moves with your eye so there is no image distortion.

* The frame of glassescan block your side / peripheral vision.

* It’s annoying when eyeglasses steam up when you come from the cold outside into a warm room.

* Sometimes contact lenses are the only solution for people who need vastly different lenses for each eye.

* An injured cornea can heal faster when its protected by contact lenses.

How Do You Go About Getting Contacts?

The next step, if you’re interested, is to to see your eye care professional to get a prescription for contact lenses since you can’t order contacts with a prescription for glasses. You’ll go through some easy vision tests that only take about 15 minutes or so. You should also get the test for Glaucoma, which is the one where there’s a tiny puff of air that gets shot into your eye. Jennifer Aniston’s character, Rachel, from Friends made a big deal about it, but it’s actually no big deal at all.

Get Your Sight Back With A Custom LASIK Procedure

Friday, April 24th, 2009

The field of medicine has seen a tremendous improvement today. LASIK eye surgery is one of the outcomes of that improvement resulted by the technological advancement in the medical field. LASIK stands for Laser assisted in situ Keratomileusis. One of the most preferred form of LASIK eye surgery is custom LASIK.

Food and Drug Administration committee has laid down certain stipulations those have to be followed before anyone is considered for Custom LASIK form of LASIK eye surgery. So everyone will not qualify for this type of treatment. The physician has to examine the patient first to confirm the suitability of the patient for this form of treatment.

Custom LASIK is not suitable to treat all forms of corneal aberrations, it can be used only to treat myopia, hyperopia and astigmatism. It is one of the most expensive forms of eye surgery procedures. The type of procedure required to treat your eye will be decided by your ophthalmologist after a close examination of your eye condition.

Custom LASIK is also called wavefront LASIK because of the wavefront tool it uses to diagnose the faults in the cornea. The wavefront tool is used to create a 3D image of the cornea. This 3D map will help the surgeon to decide the approach to LASIK eye surgery. One of the reasons why many people choose Custom LASIK is because it has very few post operative side effects.

LASIK eye surgery is performed through a series of steps including the one week preparatory period. As one of the procedures, the patient who is to undergo this surgery is asked to stop using their contact lenses. As part of the preparation, the surgeon measures the thickness of the cornea and the patient is also given antibiotics to ensure that there is no post operative infection.

During the Custom LASIK surgery the patient is kept in conscious state and only mild form of local anesthesia is administered. During the LASIK eye surgery a flap is created in the cornea. The flap created is held back while the surgeon restructures the tissues underneath the flap. Surgical laser rays are used for the operation.

After the remodeling of the inner corneal tissues the flap is placed in position. Custom LASIK does not use any additional material to hold the flap in place. The corneal tissue heals through natural means. Since LASIK eye surgery uses natural healing process, the side effects are very less.

Once the LASIK eye surgery is completed, extra care should be given to the patient to ensure that there is no attack of infections after the Custom LASIK surgery. At the post operative stage the operated eye should be protected from the exposure to bright light by wearing protective dark glasses. Though Custom LASIK procedure is one of the most popular forms of eye surgery due to its lesser post operative effects, one should not take chances. Basic care and attention that is normally given for the LASIK eye surgeries should not be missed.
