What Is Astigmatism?
Astigmatism is an extremely common eye condition that affects both children and adults. It occurs when there is an imperfection in some part of your cornea, the clear tissue that covers your iris.
The cornea is completely round. If you have astigmatism, some parts of your cornea may be rounder than others which can cause distort in the way light rays focus on your retina. Astigmatism is a reflective error because it affects the way your eyes refract, or bend, light.
Astigmatism often occurs with some other eye conditions such as nearsightedness or farsightedness. Astigmatism may be present with birth, or it may be developed after an eye injury or surgery. But please notice that astigmatism may be not caused or made worse by reading in poor light, sitting too close to the television, or squinting.
