Astigmatism is a vision condition that causes blurred vision due to an irregularly shaped cornea. It is a common eye disorder, affecting people of all ages and backgrounds.
Symptoms of Astigmatism
The most common symptom of astigmatism is blurred vision at all distances. Other symptoms can include eyestrain, headaches, squinting, and difficulty seeing at night.
Causes of Astigmatism
Astigmatism is caused by an irregularly shaped cornea. The cornea is the clear, dome-shaped surface that covers the front of the eye. When the cornea is not perfectly round, it causes the light entering the eye to be refracted in an irregular way, resulting in blurred vision.
Treatment for Astigmatism
Treatment for astigmatism usually involves corrective lenses such as eyeglasses or contact lenses. In some cases, surgery may be necessary to reshape the cornea and improve vision.
Prevention of Astigmatism
There is no known way to prevent astigmatism. However, people with astigmatism should visit their eye doctor regularly to make sure that their vision is not deteriorating.
