General EYE ADVICE

Adverse effects on vision

Temporary blurring of the vision can occur especially when shifting the focus away from the screen to other objects, and when refocusing into the distance. Permanent vision defects can also occur, such as myopia (short-sightedness) and astigmatism. The eyes often adapt to the excessive workload by becoming short-sighted, especially in younger people. In this state, the eyes no longer have to work as hard to attain clear vision at near. Refer to Part I(A) for description and Part I(B) for advice on corrective measures for myopia. Permanent changes of astigmatism can develop in some younger people, although they most often develop when middle aged people attempt to focus at near without their presbyopic correction. Refer to Part II(A): Correction of ATR Astigmatism in Children and Adults.
