The doctor said that looking at green to relieve visual fatigue means looking at the green outside the window. The farther you look, the more relaxed your eyes are. The green electronic screen has nothing to do with green, it is still an electronic screen. Video It is well known that the average person blinks 15 times a minute. Tears are evenly distributed on the surface of the eye to avoid dryness and irritation. But researchers found that people blinked less than half as often when reading, watching or using screens. And the contrast between text and background, glare and screen flicker all affect the eyes, which can lead to visual fatigue. Therefore, we can make it easier for the eyes to look at the screen in the following ways. 1. Make sure that the computer screen is about 60 cm away from your face, or arm’s length. The center of the screen should be about 10-15 degrees below eye level. 2. During the use of the equipment, take a 15-minute break every 2 hours. 3. Make sure the lighting in the room is bright enough and the device should not be brighter than the surrounding environment. 4. Regular ophthalmology.
