Things that make you go blind: Staring at your computer screen
Ophthalmologists, optometrists and other eye professionals note a seeming link between myopia, also called nearsightedness, and "near work"—visual activities that take place at a distance of about 40 centimeters (16 inches) from the eye—such as reading a book. Staring at a computer screen qualifies as well, though monitors usually are around 50 centimeters (20 inches) away.
But only a small—and mysterious—subset of people see myopic progression from near work, whether they are focusing on a computer or accounting books. "We are not very clever in identifying who [is affected] yet," says James Sheedy, a professor at the Pacific University College of Optometry in Oregon.

"Finally, eliminate any glaring peripheral light."
"Staring closely at a screen forces our ciliary muscle, which controls the shape of our lens and therefore how well we focus, to remain contracted, without rest."
