Most people associate excess time spent in front of the television or computer with eyestrain, but a new study suggests kids who spend too much time watching TV might have more severe symptoms.

Australian researchers found that a group of children who spent more time in front of a screen than being physically active had narrower arteries in their eyes.

This narrowing can be a sign of future heart disease.

The study's findings also indicate, however, that physical activity may help reverse this symptom.
