What causes dry eyes? Lack of sleep and eye fatigue are harmful to eye health

Dry eye syndrome refers to insufficient or uneven tear secretion or excessive tear evaporation, which results in the inability of tears to properly keep the surface of the eye moist.

Causes of Dry Eyes

"Dry eye" or sicca conjunctiva and keratitis (sicca conjunctivitis) is a disease in which the conjunctiva and corneal epithelium cannot maintain normal function due to the insufficient quality or quantity of the tear film in front of the cornea. There are many reasons for this disease, such as long-term use of computers, smoking, polluted air, etc., especially in winter, long-term exposure to heating is more likely to cause this disease.

Six factors that cause dry eyes

1. Due to physiological reasons such as advanced age, lack of sleep, and mental stress, the quality of tears decreases.

2. Taking some antihypertensive drugs and some tranquilizers will affect the production of tear film. For example, taking chlorpheniramine has a harmful effect on the tear film. Taking propranolol and some current contraceptives can reduce tear production.

3. Environment, such as a dry room, causes increased evaporation of tears.

4. When you engage in computer operation, driving, reading or other fine work for a long time, the number of times you blink decreases.

5. Due to contact lenses, allergic conjunctivitis, air pollution, ultraviolet rays and other reasons, the tears are reduced and the quality is reduced.

6. Long-term use of antibiotics can cause dysbacteriosis.

How to Prevent Dry Eyes

1. Live a normal lifestyle, get enough sleep and don’t stay up late.

2. Eat a balanced diet without partiality. Eat more vegetables and fruits containing vitamin ACE and less fried food.

3. Give your eyes adequate and proper rest, avoid excessive eye fatigue from prolonged use, and pay attention to the number of times you blink.

4. When washing your face, pay attention to the cleanliness of your eyelids and eyelashes. Using a hot towel for hot compresses can relieve fatigue and increase tear secretion.

5. Do not wear contact lenses for too long and remove them if you feel uncomfortable.

6. If you have any eye discomfort, please seek treatment from an ophthalmologist.

Faced with the vision loss and other complications caused by dry eyes that seriously damage eye tissue and may even cause blindness, the first thing we need to do is to strengthen prevention in daily life and improve modern people's awareness of self-care for their eyes.

Excessive use of the computer, watching TV, etc. often leads to dry eyes, fatigue, sleepiness, itching, foreign body sensation, burning pain, tight and heavy eyelids, sticky secretions, fear of wind, fear of light, sensitivity to external stimuli, and temporary blurred vision. Pay attention to eye hygiene, blink more, manage the time to look at the computer or mobile phone, and eat more foods rich in vitamin A, such as soy products, fish, milk, walnuts, green vegetables, cabbage, water spinach, tomatoes and fresh fruits. These are all effective in preventing dry eyes.
