The center of the TV screen should be at the same level or slightly lower than the eyes. When watching TV, the eye muscles are in a state of tension, and the distance between the eyes and the screen is appropriate. Many children like to stand in front of the TV while watching TV. The distance is too close, not only looks blurred, but also causes vision. fatigue. In general, the distance between the TV and the person should be 4 to 6 times the diagonal of the screen.

The contrast of the TV is too large, the brightness of the light is not uniform, the vision is more concentrated, and it is easy to cause eye fatigue. The contrast is too small, the color of the image is not clear, and it is not easy to see clearly. Some people watch TV and like to turn off the lights in the house, so the brightness of the screen is in stark contrast to the dark surroundings. When you watch it for a long time, your eyes are very uncomfortable. On the contrary, if the light in the room is very bright, the image on the screen will be gray and unclear. Therefore, when watching TV, the light in the room should not be too dark, nor too bright. You can open a soft light in the room so that your eyes are not easily fatigued.

Due to the vibration of the car and the limited space of the car, the distance and angle of watching TV in the car are not ideal. Watching TV under the conditions of improper distance and angle is easy to hurt the eyes. Therefore, in the coaches and buses, it is best not to stare at the TV screen for a long time.

In traditional Chinese medicine, angelica, white peony, etc. can supplement blood, chrysanthemum, medlar, and cassia seed have the effect of eyesight, and people who often use the eye can soak their water for tea. If you feel tired or dry, you can also drop some artificial tears to increase the lubrication of the eyes.
