Fact: There is no evidence to suggest that watching television for too long or sitting too close can damage your eyes. Young children often sit close to the television screen because they have a greater ability to focus on objects closer to their eyes than adults do. Due to this, children hold their reading material close as well. However, as they grow older, these habits usually change. If not, this may be a sign of myopia (nearsightedness). To detect possible eye problems, children should have regular eye exams.
