Some History About Contact Lenses
Are you tired and annoyed with wearing eyeglasses? Are you thinking about maybe switching to wearing contacts 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 contacts.
A Little History
The first contact lenses actually date back to the 19th century, believe it or not. They were brown glass lenses and were hard to wear but helped people that could not wear eyeglasses. The big breakthroughs came about in the 1940s and 50s when plastic lenses started being made. These early plastic contacts were made of polymethyl methacrylte, which did not allow oxygen to pass through. The new ones are rigid gas permeable and allow oxygen to pass through. Your corneas don’t get oxygen from your blood but instead get it from the air around you, so it’s important that contact lenses are breathable.
Technology in contact lenses 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.
Reasons for Wearing Contacts
People wear contact lenses for cosmetic reasons 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.
* Contacts don’t steam up like glasses do when you go from cold to warm temperatures.
* Sometimes contacts are the only solution for people who need vastly different lenses for each eye.
* The protection of contact lenses can often help someone with an injured cornea.
How Can I Get Contact Lenses if I Want to Wear Them?
The next step, if you’re interested, is to to see your eye doctor 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.
