2. Strengthen physical exercise and take part in outdoor activities. Always bask in the sun and breathe fresh air. Life should be regular, go to bed early and get up early, and keep enough sleep and proper rest. Pay attention to nutrition, don't be partial to food, don't eat snacks, eat vegetarian and vitamin-rich foods and calcium-supplemented foods, such as pork liver, milk and eggs.
3. Improve the brightness of ambient light. For the non-occupational vision decline caused by study and work in daily life, the most effective method is to pay attention to eye hygiene. Because in most cases, vision loss is related to poor light (too dark, too bright, glare, reflection, etc.). ), especially in the study, work and life with strong eye intensity, the brightness of ambient light is not suitable. Many times the light is too dark, and sometimes it is too bright.
4, pay attention to eye moisturizing. On the surface of our eyeball, there is a thin tear film, which plays a role in lubrication and keeps our eyes moist with the action of blinking. In general, blink 10-20 times per minute. 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. When you concentrate on reading or operating the computer, the blink frequency will be significantly reduced to about 5 times per minute. Staring at the screen for a long time will not only cause eye fatigue, but also lead to decreased vision. Because the eyeball is dry, the "closing eyes" between the cornea and eyelid is easy to cause abrasions, which will lead to dryness, inflammation and pain of the eyes and form dry eye syndrome.
Doing eye exercises is an effective way to prevent myopia, which should be adhered to every day. Never learned, you can gently massage the upper and lower eyes, or close your eyes to help the recovery of eye muscle fatigue.
