Technofile : Specs for nerds

Blurred vision, headaches and eyestrain are some of the familiar hazards of
working hard on a computer. You may need glasses, but standard eye tests are
printed on paper, not on fuzzy screens. Now Cosmo Salibello, an optician based
in Portland, Oregon, has developed a new eye test that simulates a computer
screen, and he reports that glasses based on this test work much better for
computer users who have eyestrain problems.
