Will watching Tv too closely to the television screen cause bad eyesight?

Personally, I don't think there is a correlation between sitting too near the screen and it resulting in having bad eyesight. That being said, I think it is uncomfortable for the eyes (e.g., the glare from the screen) to be too near a screen. I have also read that when a child constantly sits near the tv screen, it may be a sign that his/her eyesight may be affected (hence the need to be near the screen). In all, it is always good to maintain a good distance to avoid over straining the eyes. Also, always take frequent breaks to help maintain good eyesight. Look at objects in a distance once every 20mins (perhaps something outside the window) would be good for resting the eyes.

Yes because it makes the eyes work harder. There are webinars to educate parents on how to care for their kids' eyes. Please see myeyematters.com/event-registration
