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.
