1. Blink more often Blinking helps tear production. Blinking less often will directly lead to a decrease in the amount of tears. You should consciously blink more after using your eyes for a long time, such as operating a computer, driving, or reading. 2. Don’t rub your eyes with your hands Pay attention to eyelid hygiene, wash your hands regularly and don’t rub your eyes with your hands. Rest your eyes for an hour or so, close your eyes and look into the distance. 3. Use bifocal lenses People over 40 who wear glasses are advised to use bifocal lenses. Or when typing, switch to glasses with a lower prescription. Keep the distance between your eyes and the screen as close as possible to 60 centimeters. Adjust your posture so that you can keep your eyes down about 30 degrees. Such an angle relaxes the neck muscles and minimizes exposure of the eye surface to air. 4. It is best not to wear contact lenses. Wearing contact lenses for a long time will reduce the secretion of tears and make people feel that their eyes are always dry. Therefore, it is advocated to wear tangible glasses. 5. Minimize the use of air conditioning In addition to regulating the temperature, air conditioning can also dehumidify and reduce the moisture content of the air. In the air conditioning environment, the tear film evaporation rate increases, easy to make the eyes dry, astringent. 6. Artificial tears should not be used too often Points of artificial tears (nutrient solution) should not be too frequent, the best not more than 6 times a day. If it is used more than 6 times a day, the normal tear film will be washed away, thus aggravating dry eye symptoms. 7. Use of ophthalmic gel If eye ointment is left in the eye memory for a long time, the patient will feel “unhygienic” because of the greasy ointment. Moreover, the use of eye ointment may cause blurred vision and inconvenience. Ophthalmic gels are now a more desirable preparation. Ophthalmic gels are easy to use, have a cool sensation when applying the drops, and remain in the eye for a longer period of time, making them easier for patients to accept. 8. Treatment of blepharospasmic dysfunction Apply hot towels to the eyes. Do this for about 10 minutes each time. It is best to do this once in the morning, because the secretion of the blepharoplasty gland is the most vigorous at night, and the retained secretion is the most, and the hot compress can help the retained secretion to be discharged. If you have time you can do it several times a day with good results. 9. Temporarily blocking the tear ducts For moderate to severe patients who need to use artificial tears 4 to 5 times a day, blocking the tear ducts can reduce symptoms and can reduce the amount of artificial tears. Collagen plugs can be placed in the upper and lower tear ducts to temporarily block the tear ducts. The plugs are gradually absorbed over 4 to 7 days, during which time the patient’s signs and symptoms improve. For more severely ill patients, extended treatment is needed. Insoluble silicone plugs can be used to block the tear ducts for an extended period of time, and the plugs can be removed when needed. 10. Increase Nutrition Long-term computer operators should eat more fresh vegetables and fruits, and increase the intake of vitamins A, B1, C and E. In order to prevent corneal dryness, dry eyes, vision loss, night blindness, etc., should eat more food rich in vitamin A, such as soybean products, fish, milk, walnuts, bok choy, cabbage, cabbage, tomatoes and fresh fruit. Traditional Chinese medicine can treat dry eyes by internal or local application of traditional Chinese medicines that clear heat and nourish yin, and promote the production of fluids and moisturize dryness.
