Are you tired and annoyed with wearing eyeglasses? Are you thinking about maybe switching to wearing contact lenses instead? Wearing contacts 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.
Contact Lens History
Contact lenses 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 contact lenses 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 contact lens technology is still improving. People that have astigmatism can now get toric contact lenses. And people that need bifocals can now get special contact lenses made, too.
Why is it Good to Wear Contact Lenses?
Most people’s primary reasons for wearing contacts is for cosmetic purposes, but there are also other reasons:
* The lens moves with your eye and there is no distortion, unlike with glasses.
* Eyeglass frames can annoyingly block your side vision.
* Contacts don’t steam up like glasses do when you go from cold to warm temperatures.
* Some people need different types of lenses for each eye and contacts are sometimes the only solution for them.
* An injured cornea can heal faster when its protected by contact lenses.
So How Do You Get Contact Lenses?
To find out if you can wear contacts, you should go see your eye doctor and get a consultation. You can’t go and order contacts with just a prescription for glasses. It’s a different kind of prescription. When you get your exam, you’ll find it’s pretty simple and does not take very long. You’ll just do some vision testing including the test for Glaucoma, which is an important test to get. It’s just a tiny puff of air that goes into your eye.
