Practice has proved that watching television for a long time will make people have eye fatigue. How to make people not only watch television without affecting the eyes? Shanghai Normal University Department of Physics Chen Rongliang associate researcher invented RL-2 TV glasses to prevent eye fatigue effect, in order to observe this situation, we choose a primary school, wearing the above TV Glasses and glasses are not under the same conditions to watch TV for comparison, are as follows: 115 primary school students in Shanghai × × primary eye examination without eye disease, and medical history of these students in the normal family TV are different The degree of eye fatigue such as soreness, swelling, heavy, discomfort and other symptoms of eye fatigue. 45 students wearing dark RL-2 glasses, 30 students wearing light-colored RL-2 glasses, while 40 students without glasses. Let them watch TV continuously for 2 hours under the same conditions
