1, the height of the TV placed: a more appropriate height should be the center of the fluorescent screen and eye parallel or slightly lower, some parents are afraid of children moving around and watching TV, put it very high, which is not good. At the same time, we should pay attention to the obliquity of the TV, otherwise, tilt the head to look not only unclear images, and easy to cause eye fatigue, and even affect the normal development of children’s eye muscles, resulting in different degrees of strabismus. 2, the distance at which the TV is placed: the best distance to place the TV is 4-6 times the diagonal of the fluorescent screen or further away. Too close to the human eye not only to love to the brightness of the stimulus, while the image constantly flickering, eye fatigue easily. Especially for farsighted children, because the distance is too close, the adjustment and convergence function of both eyes is obviously enhanced, so that the most likely to cause eye fatigue. 3, the brightness of the TV: whether the brightness is appropriate for the convergence of the eyes, too bright or too dark are not good, the contrast between light and dark is easy to cause eye fatigue, so it is best to have a low-power electric light when watching TV, so that the room has a faint light, which is good for eye protection. 4, watching TV time should not be too long: the younger the age of watching TV time the less the better, generally require young children preferably do not watch TV, while paying attention not to gaze for hours without rest, should be in the change of program or in the broadcast of advertising time to close the eyes for a while, the eyes temporarily moved to other distant, so that the eye regulation function to do a short relief. In order to protect children’s eyes, parents should cooperate to convince their children to focus on learning and to participate in outdoor activities or sports more often.
