A Solution for Computer Eye Strain

If your vision's on the blink

(HealthDayNews) -- If you spend your working day at a computer terminal, you might want to slip out during your lunch hour and buy a bottle of eye lubricant. Be sure to get the thick stuff, because salt solutions won't help.

That's the word from the journal Experiments in Eye Research, reporting on research at the Universidad Miguel Hernandez, San Juan de Alicante, Spain.

A group of people spent half an hour looking at a computer monitor. Before they started, they were blinking at a rate of 8 or 9 per minute. At the end of the experiment, they were blinking at the rate of 12 to 13 times a minute. That meant their eyes were becoming dry and strained.

After they put in the lubricant drops, however, the blink rate dropped to about 8 blinks a minute. The salt solutions didn't produce any benefit at all.
