Modern life has been inseparable from television and computers. The paradox is that as the most important form of entertainment for people, these electronic products are very harmful to the eyes. Studies have shown that long-term watching television and computer screens, the eyes are particularly prone to problems, manifested as a significant decline in visual acuity, blurred vision, eye fatigue, dry, old want to drop the syrup, but also dizziness, headache feeling. Severe nausea, vomiting, and even blindness can occur.
Turn off the TV and not watch the computer? Faced with so many popular dramas, most people can't do it. In fact, we can also use some adjustments to reduce the damage of electronic products to the eyes.
First, adjust the brightness Some people are used to watching TV, the room lights are turned off, think that this TV screen is very bright, I feel very clear, in fact, the TV screen and the surrounding light and dark degree is very different, but will increase the degree of eye fatigue , And then form myopia. On the other hand, if the light in the room is bright, the image on the screen will appear grey and not clear. When watching TV, the light in the room should not be too dark, nor too bright. You can open a soft light or red light in the room so that your eyes are not easily fatigued.
High brightness is the chief culprit for LCD TVs that cause harm to the human eye. Behind many seemingly very clear and bright images, high-brightness stimuli are hidden. Moderate brightness refers to the brightness must be suitable for the eyes to watch the brightness, that is, in the normal living room environment, the screen color temperature in the 5500-6500, the average brightness of less than 150cdm2, not too dark, not too bright, the light to be soft.
Second, the proper distance from the TV placed and the position to watch is very important. For the location of the TV, the lighter corners should be selected as much as possible, and should be protected from light and direct sunlight. The height should be appropriate and not too high or too low. Place the height as close as possible to the eye, or slightly lower.
When watching TV, the eye muscles are in a state of tension, the distance between the eyes and the screen is appropriate, and the distance of the viewing distance should not be too close and not too far away. Too close to the viewing distance, the light received by the eyes is also increased, and it is prone to visual fatigue. The viewing distance is too far away, and the user cannot see the screen again.
In addition, you should avoid watching TV from the side, even if viewed from the side, the angle between the line of sight and the screen should not be less than 45 degrees, not to lay or face to watch TV.
Third, shorten the time Many people sit in front of the TV to sit for a long time, do not leave in the middle of the moment, even if it is advertising time to change the station to continue to see. In fact, this will cause great harm to the eyes, especially children and adolescents. For a long time watching TV screens, the number of eye blinking is reduced, and the focal length is constantly adjusted to ensure that the visual objects are clear. This causes the eye muscles to adjust, the eye's ability to adjust, and the adjustment speed to be slow, causing eye dryness, fatigue, ghosting, and vision. Blurred visual fatigue symptoms, and even complications such as dizziness, nausea, vomiting, and poor blood circulation to the body.
In addition, there will be a temporary loss of vision, which is false myopia. For young children, the eyes are relatively fragile and little attention is given to true myopia. During the watching process, you must exchange the gap between programs or advertising programs, close your eyes for a short break, or look into the distance for a while to avoid eye fatigue and affect your eyesight.
