Everyone should try not to watch the computer for more than an hour. You can look at distant and nearby objects alternately every half hour. Green plants are the best.

Continuous fatigue is very harmful to eyes. Don't let your eyes be in a state of continuous fatigue.

Step 2 blink

Blinking every day can relax your eyes. Blinking can not only relax eyes, but also relax people's spirit, which can protect eyes.

3. Insist on aerobic exercise

This seems to have nothing to do with protecting eyes, but it has a lot to do with it.

This is because the eyes and physical health interact with each other. Insisting on aerobic exercise can relax the muscles around the eyes and expand the sight distance.

Step 4 adjust the distance

If we can adjust the distance between our eyes and the computer and adopt the correct posture when using the computer, we can greatly reduce the harm to our eyes caused by watching the computer for a long time.

Step 5 adjust the light

The light of the computer must be appropriate, too bright and too dark will do harm to the eyes. Some friends are used to turning off the lights when using the computer at night.

In fact, this is not right, it will affect people's eyesight, so at night, whether reading or using the computer, the lights should be on.

Eye precautions

1, diet and nutrition

Nutrition intake should be balanced, not partial eclipse, especially the intake of vitamin B (germ rice, cereal yeast).

Lack of essential fatty acids, vitamins A, K, E and B can reduce the body's tolerance to radiation, and should be used appropriately in diet, such as milk, eggs, liver, cauliflower, cabbage, eggplant, lentils, carrots, cucumbers, tomatoes, bananas and apples.

Cruciferous vegetables such as rape, green vegetables, mustard greens, Chinese cabbage and radish are not only common delicious dishes on people's tables, but also have the function of preventing radiation damage.

Step 2 increase moisture

There is a lubricating film of tears on the surface of the eyeball, which is constantly refreshed with the blink of an eye to keep the eyes moist.

If the air is always dry or absorbed, after about 10 seconds, dry spots will appear on the tear film and the surface of the eyeball will become drier and drier.

So in general, blink 10-20 times per minute.

When you concentrate on reading or operating the computer, the blink frequency will be significantly reduced to about 5 times per minute.

Because the eyeball is dry, the eye between cornea and eyelid is easy to bruise when it is closed, which leads to dryness, fatigue, discomfort, inflammation and pain, and forms dry eye syndrome.

If you don't pay attention to it, corneal ulcers and scars may appear, which will eventually lead to decreased vision.
