Diagnosis of Astigmatism

Astigmatism is diagnosed with a routine eye examination.

In an eye with a refractive error, the light rays do not bend properly to achieve a single focus point on the retina. Instead, light rays either focus in front of the retina, or do not focus at a single point.

A process called refraction is used to measure the refractive error of the eye.

A visual acuity test is performed to determine the focusing power of the eye at different distances.

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?
