General Info about Astigmatism

Astigmatism is a refractive error which causes blurred or distorted vision. It is one of the most common vision problems. Astigmatism usually occurs when the front surface of the eye, the cornea, has an irregular curvature.

This irregular shape prevents light from focusing properly on the back of the eye, the retina. As a result, a person's vision may be blurred at all distances. Normally the cornea is smooth and equally curved in all directions. With astigmatism, the cornea is "warped", meaning it curves more in one direction and objects appear somewhat indistinct and slanted.It can occur with or without shortsightedness or long-sightedness.

When ret is done on young borns and astigmatism is present and the heredity factor is eliminated , can we then postulate that if the astigmatism is corneal,it could have formed during the development fase before birth ? Ie development in a confined space or passive baby/mom that may cause the developing front surface of the eye to in a particular "pressurized" position for too long.Also is the prevelance of higher astigmatism more with twins due "confined space".

Is it true that watching television too closely or working on a computer for a lengthy amount of time throughout the day causes astigmatism?
