Children who had the most hours of screen time, particularly in front of the television, had narrower arteries in the eyes -- a possible indicator for future heart disease risk, according to a new study. Children with the highest levels of physical activity had wider retinal arterioles. The magnitude of vessel narrowing for each hour of screen time was similar to a 10 millimeter of mercury rise in systolic blood pressure.
