Randy, not meaning to be flip, but if you have not done so, get your sons eyes checked. I used to get up real close to the screen when I was his age (Yes we had a TV when I was 5. Black and white, 3 channels, and a 17 inch screen ). Turned out to be a symptom of bad eyesight, and I should've had glasses when I was two. I still wear glasses to this day.
