What causes dry eyes? Precautions for preventing and treating dry eyes

In today's society, most of the causes of dry eyes are excessive use of the eyes, and the main cause is people who work in front of computers for a long time. Computer operators work in front of the screen for too long, and the rhodopsin on the retina will be consumed. Rhodopsin is mainly synthesized by vitamin A, which is why excessive use of the eyes leads to dry eyes.

Dry eyes refers to what is medically known as "conjunctivitis sicca", also known as dry eye syndrome. It is not a single disease, but a group of diseases caused by several completely different causes and characterized by dry eyes and less tears.

Causes of Dry Eyes

When it comes to the causes of dry eyes, in the past, it would definitely be caused by getting angry, but nowadays, most of the causes of dry eyes are caused by overuse of eyes, and the main cause is people who work in front of computers for a long time. Computer operators work in front of the screen for too long, and the rhodopsin on the retina will be consumed. Rhodopsin is mainly synthesized by vitamin A, which is why overuse of eyes leads to dry eyes.

Therefore, computer operators should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. Drink more tea, the active substances such as tea polyphenols in tea will help absorb and resist radioactive substances. Experts believe that drinking more green tea can play a certain role in anti-radiation. "Shennong's Materia Medica" lists tea among 365 kinds of medicines and says "tea tastes bitter, drinking it makes people think more, lie less, lighten the body and improve eyesight." The vitamin C and vitamin E contained in green tea, especially tea polyphenols, have strong antioxidant activity, which can remove oxygen free radicals in the human body, thereby playing a role in anti-radiation and enhancing the body's immunity. For example, the herb Fanchao can relieve eye fatigue and prevent and improve eye diseases.

In addition, tea contains carotene, which can be converted into vitamin A under the action of the intestinal wall and liver. Vitamin A has the function of nourishing the eyes, relieving eye fatigue and preventing night blindness.
