Contact Lenses for Astigmatism

Astigmatism is a common condition that affects approximately one-third of Americans. An eye affected by astigmatism has an oval shape rather than a round one, causing blurry vision. It can happen whether you are nearsighted or farsighted. The good news is that vision can be corrected with eyeglasses and contacts. At AssureVision we have years of experience identifying and addressing astigmatism for patients in Arlington Heights, IL, Barrington, IL, and the surrounding areas.

Diagnosing Astigmatism

A misshapen cornea causes light entering the eye to refract differently, causing impaired vision. Our optometrist will diagnose the condition through a routine eye exam with a keratometer. This tool assesses the curvature of the cornea. While the cause of astigmatism is unknown, researchers believe that genetics play a role. There are several forms of astigmatism including myopic (nearsightedness), Hyperopia (farsightedness), and mixed (both near and far are blurry).  Your astigmatism may get worse simply as a natural part of aging.

Contacts for Astigmatism

Contacts for astigmatism fall into two main categories: toric lenses and rigid gas permeable. Toric lenses are soft lenses similar to traditional soft contacts. They have different power in different areas, allowing the eyes to focus more easily. They are gas permeable, making them comfortable to wear. It may take several office visits to get them fitted properly. They are also available in extended wear verities. Rigid gas-permeable (RGP) lenses contain some silicone to make them more flexible and allow the eyes to breathe. For mild astigmatism, this may be the first choice for our optometrist. Many people see more clearly with this type of lens.

Other Options

Orthokeratology (Ortho-K) is a therapeutic option for mild astigmatism. This treatment involves wearing RGP lenses while you sleep. These lenses work to reshape the cornea overnight so you can see without wearing glasses or contacts during the day. The effects of the treatment only last a day or so, meaning that you will need to keep wearing the lenses overnight to maintain clear vision. For a more permanent solution, some people turn to LASIK surgery. This treatment uses precision lasers to reshape the cornea. Our eye doctor will evaluate your eyes to determine whether or not you are a good candidate for LASIK. If you are deemed one, we will refer you to a trusted eye surgeon to complete the procedure.
