Kids in front of the TV can suffer eye strain

New medical research shows children who spend most of their time looking at TVs, computers and video games may suffer from more than eye strain as adults.

A study of 6-year-olds in Australia found those children had narrower arteries at the backs of their eyes than those who are more physically active.

That can be a sign of future heart disease.

The research was published in the journal "Arteriosclerosis, Thrombosis, And Vascular Biology."
