Dr．Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache，some children don't tell their r parents，because they don't want their games or the computer to be taken away．Another part of the problem is that people blink （眨眼睛） less often when they look at the screen．A person who uses a computer or a digital product blinks about a third as much as we normally（正常地） do in everyday life．If eyes can't stay wet or are too tired，they will not be protected like normal．
