I often get asked by patients or family members, “Doctor, should I pay attention to nutrition after myopia or myopia surgery?” In fact, protecting your eyes is not only a matter of high quality eye drops, but it is more important to start with your dietary habits. The process of seeing things requires vitamin A. Optic nerve conduction requires vitamin B. Healthy blood vessels are needed to prevent old eyesight, and vitamin C and vitamin E are helpful for this. In the case of vitamin A deficiency, the eyes often feel dry and astringent, easily fatigued, and in severe cases the white surface of the eye is dry and wrinkled, even leading to corneal ulcers. Before these symptoms occur, a person’s dark vision has been reduced and dark adaptation ability is poor, which means that it is difficult to adapt when going from light to dark for a long time. Vitamin A supplementation should include more liver, milk, egg yolk, green leafy vegetables, carrots, and sweet potatoes. Lack of vitamin B2 tends to inflame the corners of the mouth, lips and tongue, and also makes the eyes dense with blood, afraid of light and prone to tears. Vitamin B2 should be supplemented with liver, kidney, milk, leafy greens, mushrooms, sweet potatoes, etc. In addition, taurine is good for relieving low vision and eye fatigue. Taurine is high in aquatic animals such as squid, shrimp, crab, oyster, shellfish, sea fish and milk. Vitamin E has antioxidant effect and has some auxiliary effect on the treatment of certain eye diseases, such as for various cataracts, diabetic retinopathy, various chorioretinopathies, optic nerve atrophy, etc. Dietary soybean oil, peanut oil and bananas are high in vitamin E content. In addition, partiality has a very obvious effect on vision development, so it is important to develop reasonable eating habits, while preventing myopia also eat less sugar. Do not be partial to food.
