Hi Vijay garu, Astigmatism is a vision condition that causes blurred vision due to an irregular shape of the cornea. Astigmatism affects one in three people in the United States. Most people have some degree of astigmatism. Slight amounts of astigmatism usually do not affect vision and do not require treatment. It may be present from birth, or it may develop after an eye injury, disease or surgery. Headaches are a common side effect of astigmatism. The reason why you may develop headaches in Astigmatism is that your eyes are straining to focus and this effort can lead to eye strain and headaches. There are excellent medicines in Homoeopathy for Astigmatism. Please call on +918885920000, to know more details. “A Healthy outside starts from the inside”.
