Types of Contact Lenses

Overview

Several types of hard and soft contact lenses are available. Consult an eye doctor who is willing to work with you to select the best type of lens for your needs and lifestyle.

Hard contact lenses

Hard contact lenses correct refractive errors, including astigmatism, with no distortion. Most hard contact lenses are made of gas-permeable materials that allow oxygen to reach the cornea. This reduces problems that may occur when the cornea doesn't get enough oxygen. These lenses are called rigid gas-permeable lenses.

Most gas-permeable lenses should be removed when you sleep. Some can be worn longer. Your doctor will tell you how long you can wear your lenses. They usually need to be replaced after 2 to 3 years of use.

Soft contact lenses

Soft contact lenses are made of soft, very flexible plastics that absorb water. Many people find them more comfortable to wear than hard lenses, but hard lenses can provide sharper vision. Soft lenses are more fragile than hard lenses.

Daily disposable lenses. These lenses are made to be worn for one day, then thrown away. You use fresh lenses each day, so you don't need to clean them. They can cost more than other lenses.

Disposable lenses. These lenses are removed and cleaned each day. Depending on the type of lenses, you replace them every 1 to 2 weeks, every month, or every 3 months.

Extended-wear lenses. These lenses are approved for longer wearing, even while you sleep. Some can be worn for up to 1 month. But your doctor may tell you to take them out and clean them each day. If you don't clean them each day, you may have a higher risk for eye problems, such as infections.
