Squinting May Cause Eye Strain and Dry Eye

Are your eyes dry and iritated, especially when doing a lot of book reading or working on computer?

Study finds that people who do a lot of visually intense work, like reading book or computer display tend to squint in order to make objects appear more clearly defined or to the glare. Apparently, squinting may lower the rate of eye blink. And blinking less may dry eyes and iritate them.

A study of 10 college students showed that the more they squinted, the less they blinked, the team at Ohio State University said.

The less they blinked, the more their eyes ached or burned, said James Sheedy, a professor of optometry who led the study.
