Astigmatism

What is it?

Astigmatism is a condition in which the cornea is not fully a circular dome. Instead the cornea is shaped more like a football. It can cause headaches and eye strains if left untreated for a while because the eye tries to focus twice as much.

What causes it?

As with nearsightedness and farsightedness, this condition is caused by many factors, including injuries and diseases. Most of the times, however, it is hereditary.

Symptoms

	1.		blurry vision
	2.		distorted vision (objects may appear stretched)

Try this test—if the some areas of the image appear lighter or blurrier than other areas, you may have astigmatism.

 

Treatment

Glasses and contacts will improve astigmatism to near perfection.

LASIK eye surgery has also proven as an effective alternative.
