What are the methods to prevent dry eyes

Nowadays, the number of electronic products is increasing, and more and more people are beginning to use electronic products excessively, which has caused eye problems. This includes dry eye syndrome. Dry eye syndrome can cause certain damage to the eyes. In daily life, we should pay attention to prevention to stay away from dry eye syndrome damage as much as possible. So, what are the prevention methods for dry eye syndrome?

1. Blink more

"Not even blinking" is used to describe someone's concentration. Ophthalmologists point out that the less you blink, the more likely you are to develop dry eyes. Because blinking helps the secretion and distribution of tears, fewer blinks directly lead to a decrease in the amount of tears. The tear film exposed to the air will evaporate quickly and lose its protective power to the eyeball. Therefore, prolonged use of the eyes, such as operating a computer, driving, reading, etc., can cause dry eyes.

Blinking is a protective nerve reflex action, and the tear layer can evenly apply tears to the surface of the cornea and conjunctiva to keep them moistened and not dry. A normal person blinks about 20 times per minute

2. Pay attention to eyelid hygiene

Pay attention to eye hygiene, wash your hands frequently, and don't rub your eyes with your hands, especially during the current high incidence season of infectious diseases such as influenza A (H1N1) and acute conjunctivitis. Hands can serve as a medium to spread germs. Take a break after using your eyes for about an hour, close your eyes, look into the distance, or look at green plants or pictures. For patients with debris or loose material on their eyelids, it is important to maintain eyelid hygiene.

3. Computer users should not neglect eye care

Young people who experience symptoms of dry eyes should seek medical attention as soon as possible. People over 40 are better off using bifocal lenses, or wearing glasses with lower degrees when typing. Try to keep the distance from the computer at least 60 cm, so that your line of sight can be kept downward at about 30 degrees. This can relax the neck muscles and minimize the area of ​​the eye surface exposed to the air.

People who work on computers for a long time should eat more fresh vegetables and fruits, and increase their intake of vitamins A, B1, C and E. To prevent dry cornea, dry eyes, decreased vision, and even night blindness, you should eat more foods rich in vitamin A, such as soy products, fish, milk, walnuts, green vegetables, cabbage, water spinach, tomatoes and fresh fruits. Vitamin C can effectively inhibit cell oxidation. The main functions of vitamin E are: lowering cholesterol, removing waste from the body, and preventing cataracts. Walnuts and peanuts are rich in vitamin E. Vitamin B1 can nourish the nerves, and green leafy vegetables contain a lot of vitamin B1. You can drink green tea or chrysanthemum tea appropriately every day, because the lipopolysaccharide in tea can improve the body's hematopoietic function, and tea also has the function of preventing radiation damage.

4. Frame glasses are the safest

Wearing contact lenses for a long time will reduce tear secretion, so people who wear contact lenses always feel dry eyes. To prevent dry eyes, it is recommended to wear contact lenses.

5. Turn on the air conditioner less often

In addition to regulating temperature, air conditioners also dehumidify, reducing the moisture content in the air. In this dry environment, the evaporation rate of the tear film increases, which can easily cause the eyes to become dry and astringent. Winter, with its dry climate, is a high incidence season for dry eyes. In summer, the weather is hot. To prevent dry eyes, be sure to open windows and ventilate regularly when using air conditioning.

6. One drop of artificial tears

Be careful not to apply artificial tears (nutrient solution) too frequently, preferably no more than 6 times a day. Because if you do it more than 6 times a day, it will wash away the normal tear film and aggravate the symptoms.

7. Eye gel is very hygienic

The eye ointment can be retained in the eye for a long time, but the eye ointment is greasy, the patient feels it is not "hygienic", there is significant blurred vision, and the patient's acceptance is poor. Eye gel is currently an ideal preparation. Eye gel has a long retention time in the eye, is very hygienic, has a cool feeling when applied, is easy to use, and has good acceptance.
