What is astigmatism:

If you have astigmatism, the surface of the eye (cornea) is not perfectly round, rather it is more oval and doesn’t allow the eye to focus clearly. The cornea is very important in helping the eye focus light rays on the retina. Astigmatism rarely occurs alone. It usually accompanies myopia or hyperopia. Children with these conditions may also have pain, watering or burning sensation in their eyes, rub their eyes or blink frequently, because of eye strain which they experience all the time, headache intensified in evening, recurrent swellings in the eye lids.
