All you need to know about
Astigmatism (uh-STIG-muh-tiz-um) is a defect in the curve of the eye that produces blurring distance and close vision.
When the front surface of the eye (cornea) or the lens inside the eye has uneven curves, astigmatism arises. The surface is egg-shaped, rather than having a single curve like a spherical ball. At all distances, this causes hazy vision.
Astigmatism is frequently present at birth and can coexist with nearsightedness or farsightedness. Often, it isn’t severe enough to necessitate corrective action. Corrective lenses or surgery are two choices for treatment if this is the case.
