How to prevent dry eye? When we study or work, we often face dry eyes caused by various electronic products or other reasons. Do you know how to prevent dry eyes? Let's have a look
How to prevent dry eye
1. Blink more 'blink without blinking' is used to describe someone's concentration. Ophthalmologists point out that the fewer blinks, the easier it is to produce dry eye. Because blinking contributes to the secretion and distribution of tears, less blinking times will directly reduce the amount of tears, and the tear film exposed to the air will evaporate rapidly and lose the protection of the eye. Therefore, using your eyes for a long time, such as operating a computer, driving and reading, will cause dry eye. Blinking is a protective nerve reflex action. The tear layer can make tears evenly spread on the surface of cornea and conjunctiva, so as to keep them wet and not dry. Normal people blink about 20 times per minute.
2. Attention should be paid to eyelid hygiene. Pay attention to eye hygiene, wash hands frequently, and do not rub your eyes with your hands. Especially in the current season of high incidence of infectious diseases such as influenza A (H1N1) epidemic and acute conjunctivitis, your hands can be used as a transmission medium to spread germs. Take a rest with your eyes for about an hour, close your eyes, look at the distance, or look at green plants and pictures. For patients with debris and shedding on the eyelid, pay attention to keep the eyelid clean.
3. Wearing frame glasses and contact lenses can really improve people's appearance to a great extent, but it brings a lot of pain. Dry eye is one of them. Wearing contact lenses for a long time will reduce the secretion of tears, so people who wear contact lenses will always feel their eyes dry. To prevent dry eye, we advocate wearing glasses on windy days, goggles when swimming and sunglasses when going out.
4. People who use computers for a long time should pay attention to the people who work with computers for a long time, especially young people. They should pay attention to the timely treatment of dry eye symptoms, reduce the time of using computers and avoid using computers for a long time. The working posture and distance are also very important. Try to keep it at a distance of 60 cm and adjust the most appropriate posture to keep the line of sight down about 30 degrees. Such an angle can relax the neck muscles and minimize the area of the eye surface exposed to the air.
5. Try to use less air conditioners and stay less in rooms with low humidity. In addition to adjusting the temperature, the air conditioner will also wet, reducing the content of moisture in the air. In this dry environment, the evaporation rate of tear film increases, which is easy to make the eyes dry and astringent. Dry winter is the high incidence season of dry eye. In hot weather, when using air conditioner, pay attention to opening windows regularly for ventilation, or place an air humidifier in the room. Keep the room humidity between 30% - 50%.

Foods containing B vitamins: one of the nutritional sources of the visual nerve. Eat more foods such as animal liver, beans, sesame, wheat germ, milk, meat and so on, which are rich in B vitamins.
Foods containing vitamin C: it can effectively reduce the damage of light and oxygen to eye lens. Foods containing vitamin C include green pepper, cucumber, cauliflower, tomato, kiwi fruit, citrus, lemon, hawthorn, grapefruit, strawberry, etc. Eat medlar and chrysanthemum: medlar and chrysanthemum are good products for eyesight and eye protection.
