Refractive error: A defect in the eye that prevents light from being brought to a single focus exact on the retina.

Retina: Light sensitive membrane at the back of the eye. Light is focused onto this membrane and the retina then transmits this information to the brain as impulses which the brain interprets as sight.

My son who is currently 6 years old has problem with his sight. When he watches TV,or if he is engrossed looking at something, he tends to look at it sideways. I am so worried that it would develop into a bad habit. I would like to know if my child's problem is also considered as astigmatism. If so, is there a way to cure the problem?

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?
