Children or others who cannot respond to a normal refraction test can have their refraction measured by a test that uses reflected light (retinoscopy).
Mild astigmatism may not need to be corrected.
Glasses or contact lenses will correct astigmatism, but do not cure it.
Laser surgery can help change the shape of the cornea surface to eliminate astigmatism, along with nearsightedness or farsightedness.
Astigmatism may change with time, requiring new glasses or contact lenses. Laser vision correction can usually eliminate, or greatly reduce, astigmatism.
In children, uncorrected astigmatism in only one eye may cause amblyopia.
Calling your health care provider
Call for an appointment with your health care provider or ophthalmologist if vision problems worsen, or do not improve with glasses or contact lenses.
