Astigmatism
Astigmatism - Glossary

Text

Astigmatism: Objects are blurred at all distances because the shape of the cornea is not uniform.

Contact lenses: Lenses which fit directly on the eyeball under the eyelids.

Cornea: The clear tissue in front of the eye resembling a crystal of a watch.

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.

Sclera: The firm white fibrous membrane that forms the white part of the eye.

Visual Acuity: Clarity of vision, with corrective glasses.

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?
