What Causes Astigmatism?

Astigmatism can be hereditary and is often present at birth. Astigmatism can also result from pressure from the eyelids on the cornea, incorrect posture or an increased use of the eyes for close work.

How is Astigmatism Treated?

Almost all degrees of astigmatism can be corrected with properly prescribed eyeglasses or contact lenses. For a person with only a slight degree of astigmatism, corrective lenses may not be needed at all, as long as other conditions such as nearsightedness or farsightedness are not present. If the astigmatism is moderate to high, however, corrective lenses are probably needed.

Corrective lenses can be either eyeglasses or contact lenses. For astigmatism, special corrective contact lenses called toric lenses are prescribed. Toric lenses have greater light bending power in one direction than the other. After taking a few measurements, Dr. Sheiner will determine the ideal toric lens prescription for your astigmatism.
