"What is the ideal television viewing distance?

The bigger the TV the farther you should sit from it in order to view the best quality image and prevent eyestrain. To find out the ideal viewing distance measure your TV screen height in inches, then multiply by six. If you have a high definition TV multiply by three to five. Consider angle at which you view the TV as well. It should be mounted flat on a stand. While seated, your eyes should be level with the middle of the screen. The best seats are the ones directly in front of the screen, since many TV do not have a wide viewing angle. Your worries about potential eye problems from TV viewing are justified. Prolonged TV viewing at close range and with inadequate lighting can cause eyestrain. It is also important to consider that your nieces may be moving closer to the TV because they already have a vision problem. Nearsightedness is becoming a more common problem among children, and is occurring at an earlier age. The reason is because young people are exposed earlier to a lot of near work activities not just television but also reading, jigsaw puzzles, video games, computers, arts and crafts. It unfair to blame vision problems on TV even as we push children to read more at an earlier age, and we allow them to spend hours each day on computers......
