Learn all about Contact lenses
Contact lenses, like eyeglasses or laser eye surgery, can correct your nearsightedness, farsightedness, and astigmatism. Of the people who need vision correction in the United States, about one in five wear contact lenses.
While some people enjoy the fashion statement of eyeglasses, others prefer their appearance without them. Contact lenses can achieve this without irreversible surgery. Contact lenses can also provide a full field of unobstructed vision, which is good for participation in sports. |

Contact lenses have been around for more than 100 years. During that time, many advancements have been made that allow just about everyone to wear contact lenses. If you were told in the past that you couldn't wear contact lenses, odds are that's not true today. There are more convenient and healthy contact lenses options than ever.

If you're new to contact lenses, your first step is to see an eye doctor. In the United States, contact lenses are a prescription item, just like pharmaceuticals. They must be prescribed and properly fitted by an eye care professional (ECP). Your ECP will evaluate your visual needs, your eye structure, and your tears to help determine the best type of lenses for you.
What are contacts made of?
Classified by material, there are three types of contact lenses:
|
- Hard lenses are made from PMMA — also known as Plexiglas or Lucite. These lenses are virtually obsolete and rarely used.
- Soft lenses are made from gel-like, water-containing plastics, and are most common. They're a bit larger in size than your iris (the colored part of your eye).
- GP lenses, also known as RGP or "oxygen permeable" lenses, are made from rigid, waterless plastics and are especially good for presbyopia and high astigmatism. These lenses are usually about eight millimeters in diameter, which is smaller than your iris.
From the introduction of soft lenses in 1971 until relatively recently, most lenses brands have been made from "hydrogel" plastics. Recently, new silicone hydrogel contact lenses have been introduced. They have become the contact lenses of choice for many eye care practitioners, because they allow more oxygen to pass through the lenses to the eye, and they are less prone to dehydration. |
