RISK: TELEVISION TIME AND CHILDRENS' EYES:

Children who spend more time in front of television and computer screens and less in outdoor physical activity have narrower blood vessels in their eyes, a new study has found.  In adults, constricted blood flow to the eyes have been linked to an increased risk of cardiovascular disease.  Scientists in Australia studied 1942 six year-olds and questioned their parents about the amount of television exposure.  After adjusting for a variety of health factors, they found that blood vessels in the eyes of children who watched the most TV were slightly smaller in diameter than those in children who watched the least amount.  However, to really understand the effects in children, the children must be monitered for future narrowing.
