If you've been wearing eyeglasses for a number of years, like me, then you may be wondering if contacts are right for you? There are a number of advantages to wearing contact lenses over eyeglasses and you may find that you like them better. Take a few minutes to read some good information about contacts and how to get them for yourself.
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 glasses. 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.
Contact lens technology continues to improve as we're seeing new kinds of lenses being made for people that have astigmatism or for people that need bifocal lenses.
Why is it Good to Wear Contacts?
Most people's primary reasons for wearing contact lenses is for cosmetic purposes, but there are also other reasons:
* Unlike eyeglasses, the lens moves with your eye so there is no image distortion.
* The frame of eyeglassescan block your side / peripheral vision.
* It's annoying when eyeglasses steam up when you come from the cold outside into a warm room.
* Some people need different types of lenses for each eye and contacts are sometimes the only solution for them.
* The protection of contacts can often help someone with an injured cornea.
How Can I Get Contacts if I Want to Wear Them?
You should go see your eye care professional and get an eye exam and consultation. You cannot order contact lenses with a prescription for eyeglasses. It's a much different kind of prescription that you need. You'll go through some simple vision tests which only take about 10-15 minutes usually. You should also get tested for Glaucoma, if possible - that's the test that Rachel on Friends didn't like because it shoots a tiny puff of air into your eye. It's really not that bad and its an important test to get.
