Causes of astigmatism:
- Lid swellings such as chalazia
- Corneal scars
Diagnosing astigmatism:Your eye doctor can conduct a refractive evaluation to determine whether your eyes focus light rays exactly on the retina at distance and near. A visual acuity test will determine your ability to see sharply and clearly at all distances. Your eye doctor will also check your eye coordination and muscle control, as well as your eyes’ ability to change focus. All of these are important factors in how your eyes see.
Treatment of astigmatism:Glasses and contact lenses are used by many for the temporary treatment of astigmatism. However, there are a number of vision correction procedures that can surgically reduce or eliminate astigmatism.
