It is one of the most common
The exact cause of astigmatism is unknown. It is usually present from birth.
Astigmatism usually occurs when the front surface of the eye, the cornea, has an irregular curvature. This irregular shape prevents light from focusing properly on the back of the eye, the retina. As a result, a person's vision may be blurred at all distances. Undetected astigmatism is usually associated with fatigue and eyestrain. It can occur with or without shortsightedness or long-sightedness.
An ophthalmologistcan diagnose astigmatism with a thorough eye exam. Almost all degrees of astigmatism can be corrected with eyeglasses or contact lenses. Another method for correcting astigmatism is refractive or laser eye surgery i.e. by changing the shape of the cornea.
