Like LASIK and glasses, contact lenses can correct nearsightedness, farsightedness and astigmatism. Contact lenses have been around for more than a hundred years. Many advancements have been made that allow just about everyone to wear contact lenses. If you were told years ago that you couldn’t wear contact lenses, odds are that isn’t the case today. Schedule an appointment with Benjamin Eye Care today to see what your options are for contact lenses.
What are contact lenses? What are they made of?
Contact lenses are medical devices worn directly on the cornea of the eye to help correct refractive errors by adding or subtracting focusing power to the eye’s cornea and lens. There are several types of contact lenses.
- Soft contact lenses: these are the most common type prescribed. They are made of materials that incorporate water, making them soft and flexible. It also allows oxygen to reach the cornea.
- Gas-permeable lenses: also known as “RGPs”, these lenses are “hard” and made of plastics combined with other materials, like silicone and fluoropolymers, which allow oxygen in the air to pass directly through the lens.
- Hard lenses: made from rigid plastic material called PMMA that does not allow oxygen to reach the eye. These have virtually been replaced by RGP lenses and are very rarely prescribed today.
Wear time and Disposal Intervals for Contact Lenses
There are two types of lenses classified by wearing time:
- Daily wear lenses- must be removed nightly. Daily wear lenses should never be worn as extended-wear lenses. Misuse can lead to temporary and possibly threatening damage to the cornea.
- Extended wear lenses- can be worn overnight, usually for seven consecutive days without removal.

Conditions that would prevent an individual from being able to wear contact lenses include:
- Frequent eye infections
