Types of Contact Lenses
Contacts float on the tear film that covers your cornea. They can be made from many kinds of plastic, each with its own benefits. The two most common types of contact lenses are hard and soft.
Hard Contact Lenses
The most common type of hard contact lens is a rigid gas-permeable (RGP) lens. These lenses are usually made from plastic combined with other materials. They hold their shape firmly, yet they let oxygen flow through the lens to your eye.
Soft Contact Lenses
Most people choose to wear soft contact lenses because they tend to be more comfortable and there are many options to choose from. Here are some types of soft lenses.
Daily Wear Contacts
Daily wear contacts go in your eyes when you are awake and are removed when you go to sleep. Many are disposable, meaning that you wear a new pair of contacts each day. Or you might choose contacts that last longer and only need to be replaced once a week, every two weeks, or every month.
Extended Wear Contacts
You can wear extended wear contacts while you sleep, but they need to be removed for cleaning at least once a week. Fewer eye doctors recommend these contacts because they increase the chance of getting a serious eye infection.
These lenses can correct vision for people with astigmatism, though not as well as hard contact lenses. Toric lenses can be for either daily or extended wear. However, they often cost more than other types of soft contact lenses.
Colored (Tinted) Contacts
Vision-correcting contact lenses can be tinted to change the color of your eye. You can get them as either daily wear, extended wear, or toric lenses.
Decorative (Cosmetic) Contacts
These lenses change the look of your eye but do not correct vision. 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. This means cleaning them regularly and thoroughly as directed.
Contacts for Presbyopia
Presbyopia contacts are designed to correct the normal vision problems people get after age 40, when it becomes harder to see close objects clearly. There are different options for these corrective lenses.
These contacts do not have a prescription built into them. Instead, they cover the surface of your cornea for comfort after an injury or surgery.
