Astigmatism
Astigmatism is a vision condition that occurs when the front
surface of your eye, the cornea, is slightly irregular in shape. This irregular
shape prevents light from focusing properly on the back of your eye, the retina.
As a result, your vision may be blurred at all distances.
People
with severe astigmatism will usually have blurred or distorted vision, while
those with mild astigmatism may experience headaches, eye strain, fatigue or
blurred vision at certain distances.
Most people have some degree of astigmatism. A comprehensive optometric
examination will include testing to diagnose astigmatism and determine the
degree.
Almost all levels of astigmatism can be optically corrected with properly
prescribed and fitted eyeglasses and/or contact lenses.
Corneal modification is also a treatment option for some patients.
