What is astigmatism?
Astigmatism occurs when the front surface of your eye (cornea) or the
lens inside the eye is slightly irregular in shape, resulting in vision
being blurred at all distances. Astigmatism is not a disease, but is
actually a vision condition that is quite common.
What causes astigmatism?
When the front of your eye or the lens inside the eye is more oval than
round, light does not focus properly on the back of your eye (retina).
The causes of this irregular shape are unclear. In some cases, it may be
hereditary or it may result from such factors as pressure of the eyelids
on the cornea.
How common is astigmatism?
Most people have some degree of astigmatism. However, only moderate to
highly astigmatic eyes may need corrective lenses.
What are signs/symptoms of astigmatism?
People with severe astigmatism will usually have blurred or distorted
vision. Those with mild astigmatism may experience headaches, eye
strain, fatigue or blurred vision at certain distances.
How is astigmatism diagnosed?
A comprehensive eye examination by your doctor of optometry will include
tests for astigmatism.
Can astigmatism by corrected?
Almost all levels of astigmatism can be optically corrected with
properly prescribed and fitted eyeglasses or contact lenses.
Does astigmatism get progressively worse?
Astigmatism may increase slowly. Regular optometric care can, however,
help to insure that proper vision is maintained.
How will astigmatism affect my lifestyle?
You may have to adjust to wearing eyeglasses or contact lenses if you do
not wear them now. Other than that, astigmatism probably will not
significantly affect your lifestyle at all.
