Astigmatism is a common vision problem that usually appears early in life and in conjunction with nearsightedness or farsightedness. This form of refractive error in your eye is the result of an irregularly shaped cornea. In order to have clear vision, your cornea needs to be symmetrical and round. Astigmatism develops because your cornea is oval-shaped with steep or flat surfaces.

Symptoms of Astigmatism
The mechanics of your vision deal with the way your eye focuses light. In a regular eye, light is focused on a single point of your retina giving you clear vision. Astigmatism prevents your eye from properly focusing light and scatters it across several points in front and/or behind your retina.
This vision error can cause several symptoms including:
- Blurred vision
- Distorted vision
- Eye strain
If you’re experiencing any of these symptoms, schedule an eye exam with Dr. Wilmarth to see if you have astigmatism.
Types of Astigmatism
The three astigmatism forms include:
- Myopic Astigmatism. This version involves nearsightedness (myopia) on one or both of your principal meridians. The light coming into your eye is focused before it reaches your cornea. This causes blurred or distorted vision because your eye is either too curved or too long. Myopic astigmatism can be treated with contact lenses, an intraocular lens or refractive surgery.
- Hyperopic Astigmatism. Farsightedness (hyperopia) happens when your eye is short and not curved enough for optimal eyesight. Light is focused in the back of your eye causing poor vision. Astigmatism combined with farsightedness means that one or more of your meridians cause close objects to become blurred.
- Mixed Astigmatism. A mixed astigmatism involves both farsightedness and nearsightedness. Each form of vision impairment occurs on one meridian.
Astigmatism could be the result of genetics, disease, eye injury or surgery.
