Nutritionist Shi Rui talks about eye care

Water: transparent cornea is most afraid of dryness. The tears secreted by the lacrimal gland nourish the cornea, and the lens is also immersed in water, which actually maintains the circulation and metabolism of the eye. Therefore, both young and old people should develop the habit of drinking more water, so that the eyes can be properly maintained and moistened, which can improve the dryness of the eyes.

Protein and vitamin A: Lack of protein and vitamin will cause cataracts, night blindness and keratopathy. To develop the habit of eating lean meat, fish and eggs, vegetarians should supplement milk and soy products. They often eat animal liver, carrots, garlic seedlings, coriander, rape, spinach and other foods rich in vitamin A.

Vitamin C: Vitamin C can reduce the damage of oxygen in light to the lens. Eat more fruits and vegetables.

Vitamin B: It is an important substance involved in the metabolism of nerve cells, including the optic nerve, and has the function of protecting the eyelid, conjunctiva and cornea. When lacking or insufficient, it is easy to make eyes dry and astringent, bulbar conjunctiva congestion, eyelid inflammation, photophobia, blurred vision, visual fatigue, and even optic nerve inflammation. Foods rich in B vitamins include peanut, bean, millet animal viscera, meat, eggs, fish, rice bran, peas, etc.

Other trace elements: zinc, selenium, etc. are involved in the synthesis of various substances in the eyes and regulate their physiological functions.

Drink more water, eat more vegetables and fruits: replenish eye moisture. In a dry environment, the tear layer evaporates in a few seconds, which is an important reason for dry eyes. Drinking more water can play a good role in alleviating this symptom.

Tonifying liver and kidney: lack of qi and blood, loss of liver and kidney essence and qi, easily lead to myopia. It is suggested that in terms of diet, we should eat more foods or drugs that can benefit the liver and kidney, and the shrewd, such as black beans, black sesame, pig liver, medlar, chrysanthemum, etc.

Keep the office environment wet: put air humidifiers indoors to keep a certain humidity indoors, which is good for eye protection. Open windows regularly for ventilation to ensure the circulation of indoor air and proper humidity.

Eye application therapy: mulberry leaf has the effect of nourishing liver and improving eyesight. Take 30g fresh mulberry leaves, wash them, mash them into mud, divide them into two parts and spread them on two pieces of gauze cloth, then apply them on the eyelids with eyes closed, 15 minutes each time.

The eyes are very dry, so it is better to take vitamin A capsules or cod liver oil directly. Because the conversion rate of carotene is slow, and the conversion rate varies from person to person, and vitamin A is absorbed and utilized quickly. Do not take too much every day to avoid cumulative poisoning.
