Although many a wife has told this tale, there is no evidence to support this claim. The American Academy of Ophthalmology actually concludes that the eye muscles simply accommodate the shape according to the distance between its lens and the object. Close-range viewing does cause the eyes to blink less frequently; therefore, the dryness may lead to eyestrain and fatigue. However, it does not cause any permanent damage. Moreover, children often focus better up close without eyestrain than adults and therefore may choose to view the clearer objects of a nearer screen.
[Another busted myth: reading in poor light will damage eyesight.
What we need is a spring cleaning of these dusty old wives and their spun tales!]
