CONTACT LENSES are medical devices, used to correct a wide range of vision issues, that need to be properly fitted by an eye care practitioner.
* In the United States, contacts can be legally purchased
Contact lenses are made of many different types of plastic, but they are divided into two main groups:
SOFT: Soft contacts contain from 25% to 79% water, are easy to adapt to and quite comfortable.
RIGID GAS PERMEABLE (RGP lenses, now called GP lenses): Rigid gas permeable contact lenses take longer to adapt to, but are more durable and more resistant to deposit buildup. They tend to be less expensive over the life of the lens (but the upfront cost is higher) and can offer some people sharper vision than they would have with soft contacts.
* Contact lens wear is at an all time high, that's because technology continues to improve materials and designs. One big buzz the last few years is contact lenses made from new silicone hydrogel materials.
* These "super-permeable" lenses can deliver five or six times as much oxygen to your eye than conventional disposable lenses, providing health and comfort benefits. Some silicone hydrogel lenses are approved for 30 days of continuous wear, and some brands are now available as a bifocal/multifocal.
* This means people with a wide range of vision problems can now successfully wear contacts, including most people with astigmatism and even bifocal wearers! And don't forget, there are lenses that can enhance or even change the Color of your eyes, as well as a contact lens line called Wild Eyes for an added dramatic effect perfect for Halloween!
