Watching TV on the computer and reading novels are equally harmful to the eyes because both activities may cause eye fatigue, dryness, vision loss and other problems. However, the difference between watching TV and reading novels was the viewing distance and screen size. Television screens are usually larger than computer screens and are usually placed further away from the eyes. Watching TV for a long time may cause eye fatigue and dryness because the eyes need constant adjustment to maintain the line of sight and focus. In addition, the brightness and contrast of the TV screen are usually low, which may damage the retina of the eye. In contrast, when reading a novel, the eyes usually had to be kept closer to the screen, and the brightness and contrast of the screen were usually higher. Therefore, reading novels would not cause eye fatigue and dryness like watching television. However, when reading a novel, one's eyes needed to constantly adjust and focus, and one might also feel some discomfort. Therefore, whether watching TV or reading novels for a long time, exposure to the screen may cause eye fatigue and dryness. It is recommended to rest your eyes away from the screen every once in a while and use eye protectors appropriately.
