Astigmatism

Astigmatism is a vision condition that occurs when the front surface of the eye, the cornea, is slightly misshapen. This prevents the image of an object from focussing accurately on the retina. As a result, vision remains blurred at all distances. Astigmatism may accompany near sightedness or farsightedness. People with severe astigmatism will usually have blurred or distorted vision. While those with mild astigmatism will experience headache, eyestrain, fatigue or blurred vision at certain distances.
