Refractive Error Correction

Like eyeglasses, contact lenses correct vision problems caused by refractive errors. A refractive error is when the eye does not refract (bend or focus) light properly into the eye resulting in a blurred image.

Contacts can improve vision for people with these refractive errors:

• Myopia (nearsightedness)
• Hyperopia (farsightedness)
• Astigmatism (distorted vision)
• Presbyopia (changes to near vision that normally happen with age)

Hard Contact Lenses

The most common type of hard contact lens is a rigid gas-permeable (RGP) lens. These lenses are usually made from silicone combined with other materials. They hold their shape firmly, yet they let oxygen flow through the lens to your eye.

RGP lenses are especially helpful for people with astigmatism and a condition called keratoconus. This is because they provide sharper vision than soft lenses when the cornea is unevenly curved. People who have allergies or tend to get protein deposits on their contacts may also prefer RGP lenses.

Soft Contact Lenses

Most people choose to wear soft contact lenses. This is because they tend to be more comfortable and there are many options. Some types of soft lenses include:

Daily wear contacts

You wear these when you are awake and remove them when you go to sleep. Many are disposable (daily wear), while others may last a week, two weeks, or a month. Some ophthalmologists recommend disposable daily wear contacts if used only occasionally.

Extended wear contacts

You can wear these while you sleep, but they must be removed for cleaning at least once a week. Fewer eye doctors recommend these as they increase the chance of getting a serious eye infection.

Toric contacts

These can correct vision for people with astigmatism, though not as well as hard contact lenses. Toric lenses can be for daily or extended wear, but often cost more than other types of soft lenses.

Colored and Decorative contacts

Vision-correcting contact lenses can be tinted to change the color of your eye. Decorative (cosmetic) lenses change the look of your eye but do not correct vision. They are also used to hide certain eye problems present from birth or caused by injuries. Even though they do not correct vision, you need a prescription for decorative contacts. To avoid getting dangerous eye infections, these lenses must be treated like prescription contacts.

Other Specialty Lenses

Contacts for Presbyopia

Designed to correct normal vision problems after age 40. Options include bifocal or multifocal lenses, and monovision correction where one eye wears a near vision lens and the other wears a distance lens.

Hybrid and Scleral Lenses

Hybrid lenses have a rigid center surrounded by a soft outer ring, combining crisp vision with comfort. Scleral lenses are large gas permeable (GP) lenses that stretch over the cornea and rest on the sclera. Their large size helps correct vision problems caused by an irregularly shaped cornea (corneal scars, keratoconus or surgery).

Bandage Lenses

These contacts do not have a built-in prescription but cover the surface of your cornea for comfort after an injury or surgery.

Safety Advisory & Note

Your eyes are very important—and very delicate. Make sure your contact lenses are medically safe and FDA-approved. Contacts are medical devices that require a prescription from an eye care professional. They are not fashion accessories or cosmetics.

Non-prescription costume contacts can cause cuts, open sores and potentially blinding infections. In addition to suffering severe pain, you may need surgery (such as a corneal transplant) or, in some cases, you could go blind.
