Are you tired and annoyed with wearing glasses? Are you thinking about maybe switching to wearing contact lenses 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 contacts.
A Little History
Contacts actually date back into the 19th century if you can believe it. The first ones were made of brown glass and were quite difficult to wear as you might imagine but they were helpful to people with particular eye problems that could not wear glasses. Some significant breakthroughs in the 1940s and 1950s when plastic lenses were introduced. These new contacts were made of a hard plastic called polymethyl methacrylte, which did not allow gas like oxygen to pass through them. The better contact lenses that we have today are rigid gas permeable, which do allow oxygen to easily pass through them. This is important because the cornea of your eye needs oxygen from the air since it does not get oxygen from your blood.
We’ve seen in the last few years how technology in contact lenses is still improving. People that have astigmatism can now get toric contact lenses. And people that need bifocals can now get special contacts made, too.
Reasons for Wearing Contacts
Most people’s primary reasons for wearing contact lenses is for cosmetic purposes, but there are also other advantages:
* Unlike glasses, the lens moves with your eye so there is no image distortion.
* Your side vision is not obstructed with the frame of the glasses.
* Eyeglasses can often steam up when you go from a cold to warm temperature room.
* Sometimes contact lenses are the only solution for people who need vastly different lenses for each eye.
* The protection of contacts can often help someone with an injured cornea.
How Do You Go About Getting Contact Lenses?
You should go see your eye doctor 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.
