If you have astigmatism in one eye do you always have it in the other eye?
Two forms of astigmatism exist. Regular astigmatism is a type that is corrected by glasses or soft contact lenses, and irregular astigmatism is typically created by various eye conditions or eye diseases and is corrected by hard contact lenses or surgical options. While astigmatism is most often bilateral (both eyes) that is not always the case. In addition, astigmatism is rarely exactly the same amount in both eyes. Some eye conditions can lead to asymmetrical amounts of astigmatism between two eyes. Even something as simple as a large stye (hordeolum) or chalazion (blocked oil gland in the eyelid)can push on the eye and induce temporary astigmatism in one eye from pressure on the wall of the eye that distorts the cornea shape.
