Remind the computer: sore eyes will cause disease

I want to know if you are also suffering from computer vision syndrome. Is it easy to think that your eyes are always dry and sore? If yes, be careful! Sour eyes are one of the symptoms. In addition, eye fatigue, headache, dual-image vision (that is, two images), blurred screen images, swollen eyes, and even inflammation are all symptoms of computer vision syndrome.

The eyes are sour because they are close to the computer, and the eyes are dry. "Acid" can cause eye fatigue and even nerve fatigue, which is why computers have a headache for a long time. The reason is that the eyes are too focused on the computer, resulting in fewer blinking times and rapid tear evaporation.

In addition, most office rooms are equipped with air-conditioning systems, so the humidity is low, which accelerates the evaporation of tear water. If you happen to be a contact lens, there are only four words to describe-"worse", which is the main cause of acquired "dry eye syndrome. Dry will not only cause hypoxia, red eyes, lack of tear moisturizing eyes will also be unable to sterilization, and may be inflamed.

How to protect your eyes from injury?

As the saying goes, "prevention is more important than treatment". In addition to eye exercises to eliminate fatigue and relax eyes, what other methods can be used to prevent "computer vision syndrome?

1. Proper eye rest: the pupil is enlarged in the natural state, and the pupil is scaled out, indicating that the pupil is under pressure. The pupil is too strong and close-up, and the eye needs to be stretched out. Therefore, Dr. Zhang suggested that you should take at least five minutes off every 30 minutes to watch the computer. During the rest, you can turn your eyes or look at the distance. In short, you should not stare at the computer, let your eyes relax properly.

2. Suitable computer working environment: Adjust the light to make the eyes comfortable, but because the computer itself is a luminous body, do not let the light source directly shine on the screen to avoid reflection.

3. Correct posture: keep the body and feet in a vertical sitting posture, the computer screen is best placed in the eyes below the level of about 10 to 15 centimeters, that is, let the eyes look down on the computer. The distance between the screen and the eyes should be at least 60 cm for a 14-inch screen. If it is a 15-inch screen, it is best to have a 70 cm distance.

4. Wear proper glasses: Dr. Zhang believes that sufficient degrees are used to help you see the scenes clearly. However, when using computers, people with a degree over 200 degrees should be able to wear glasses that are about 150 degrees lower than the original degree. If there is no myopia, it is better to stay a little farther away from the computer than normal.

5. Eye supplements: You can eat more foods rich in vitamin A, such as carrots, spinach, and tomato.

6. computer goggles: Although Dr. Zhang believes that the current computer radiation has been reduced to a minimum, if it is for office workers who have to work in the computer for more than 8 hours a day, select a goggles to isolate the screen radiation, it is still a good practice for the eyes.

In addition, Dr. Zhang said that "flying a kite" and "watching movies" are only helpful to the eyes. Flying a kite is a long-distance view of things. You may still think about it, but what about watching a movie?

"Because of the effect of 'video'," said Dr. Zhang. When watching a movie, all the indoor lights are turned off. At this time, the pupil is enlarged. In addition, the screen of the movie is very large. If you can sit in the middle and back rows, it is best to have a distance from the screen, in this way, the eyes of a movie will be quite comfortable. Therefore, Dr. Zhang strongly recommends that you go to the cinema to watch movies while you are on vacation.
