| astigmatism |
A refractive error usually caused by toric (like a rugby ball) curvature of the front surface of the eye. Instead of being brought to a focus at one point at the back of the eye, light is focused in two lines at right angles to each other. Astigmatism is easily corrected with glasses to bring the two lines to one point focus.

| astigmatism |
An irregular curvature of the cornea. If it is shaped more like a football rather than a basketball, light is not sharply focused on the retina. This results in blurry vision for both distance and near. LASIK can help correct this disorder.
