Squinting Leads To Dry Eye Syndrome

Thursday, 01 December 2005 12:00 AM

Squinting at a computer leads directly to the Dry Eye Syndrome, according to a new study from Ohio State University.

The study found that even slight squinting cuts the amount of blinking you do in half, leading to irritation, burning, and tearing.

"People tend to squint when they read a book or a computer display, and that squinting makes the blink rate go way down," said lead researcher James Sheedy, a professor of optometry at Ohio State University.

The unpleasant condition is estimated to affect nearly 5 million Americans.

"Blinking rewets the eyes," Dr. Sheedy explained. "So if your job requires a lot of reading or other visually intense work, you may be blinking far less than normal, which may cause eye strain and dry eye."

The researchers asked college students to squint at different levels and found that the more intensely the students squinted the less they blinked and the more serious their dry eye became.

According to the report, published in a recent issue of the journal Optometry and Vision Science, slight squinting cut blinking from 15 to just over 7 blinks per minute, but intense squinting cut blinking to less than 4 per minute.

Dr. Sheedy is looking for the underlying relationship between slowed blinking and dry eyes - but for he said that for the present the dry eye syndrome is usually treatable with over-the-counter eye drops.
