Types of Contact Lenses
What's New in Soft Contacts?
No doubt you have heard of the term "disposable lenses". "Disposables" is used as a catch-all term to describe lenses that are designed to be discarded by the user on a planned basis, before they are overly soiled, damaged or lost.
The most popular type of disposable lens is the 2-week disposable lens. It is worn on a daily wear basis and cleaned each night with a simple one-step multipurpose solution. At the conclusion of two weeks, the lens is thrown away and a fresh lens is applied to the eye. Since the arrival of this lens, the frequency of contact lens related eye infections and complications has decreased dramatically.
Do People Still Wear Hard Lenses?
Yes! Actually, hard lenses have been replaced with rigid gas permeable (RGP) lenses. They are still a "hard" lens but the material has been modified to allow gases such as oxygen to pass through the plastic. Gas permeable lenses provide the cornea with a good supply of oxygen and do not typically break or tear as easily as soft contact lenses. There are many advantages to RGPs and we counsel each patient concerning the features of RGPs vs. soft lenses when a patient decides to wear contact lenses for the first time, or when they simply need to be refit.
