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.
