Improve diet and protect eyesight;
(1) Eat less sweets: After sweets are digested, a large number of acidic metabolites are produced in the blood, which neutralizes calcium and magnesium ions in the blood, resulting in a decrease in blood calcium. Calcium deficiency will affect the scleral function, reduce the elasticity of the eye wall, lengthen the axial length, and lead to myopia.
(2) Eat more foods rich in vitamin B2: Without vitamin B2, eyes are afraid of light, tears, itching and burning, which will lead to visual fatigue and myopia over time. Foods rich in VB2 include: animal heart and liver, lean meat, eggs, milk, various green leafy vegetables and yeast.
(3) Eat more foods containing chromium: Studies show that the occurrence and development of myopia is closely related to the lack of chromium in diet. Chromium is one of the essential trace elements for human body. When the human body is deficient in chromium, the insulin function is obviously reduced, thus the blood sugar is increased, which leads to the change of blood osmotic pressure, and then the osmotic pressure of crystals and aqueous humor is also changed. When the osmotic pressure of aqueous humor is lower than that of the lens, aqueous humor enters the lens, making the lens bulge, increasing diopter and blurring the image, thus causing myopia. Chromium-containing foods: all kinds of beans, seafood, liver, lean meat, etc.
(4) Avoid alcohol and tobacco: Long-term smokers will have "tobacco toxic amblyopia". At first, my eyes were uncomfortable, but later my vision decreased and I couldn't distinguish colors clearly. In severe cases, it will lead to optic neuritis or blindness. Modern research has confirmed that cyanide in tobacco accumulates in the body, and when it exceeds a certain "critical value", chronic poisoning will occur, causing systemic reactions, with the most obvious damage to the eyes. Alcohol in wine will cause conjunctival congestion, and long-term effect will cause local tissue malnutrition. Excessive drinking will consume VB, leading to corneal conjunctiva dryness, optic neuritis and lens opacity.
(5) Chinese medicine therapy: Chinese medicine believes that myopia is mainly caused by deficiency of liver and kidney and deficiency of qi and blood. Regular consumption of foods that tonify liver and kidney, benefit qi and blood, such as animal liver, kidney, eyes, fish, longan, grapes, mulberry, sesame, walnut, cassia seed, medlar, etc., has a certain effect on preventing and treating myopia. Such as: steamed chicken with longan and red dates, sesame walnut milk honey drink, oyster mushroom seaweed soup, bean kernel japonica rice eight-treasure porridge.

People who are not suitable for wearing sunglasses: glaucoma, night blindness, color blindness and retinitis.
Special reminder:
1. Sunglasses can block ultraviolet rays because the lens is coated with a special layer. Inferior sunglasses not only can't block ultraviolet rays, but also make the transmittance of the lens drop seriously, make the pupil bigger, and ultraviolet rays will be injected in large quantities, which will damage the eyes. In addition, inferior lenses can also cause symptoms such as nausea, forgetfulness and insomnia.
