Eye protection can eat 2 types of food 1, chromium food Chromium is also a necessary mineral element in the human body. Its role in the development of the eyeball is to maintain a balance between its osmotic pressure. Otherwise, it can cause the lens to bulge and become convex, resulting in an increase in the refractive power of the eye and thus becoming myopic. According to experts' estimates, children need approximately 50-200 micrograms of chromium per day. Chromium-containing foods include: cereals, meat, cheese, egg yolk, etc. They should be given to children. 2, calcium foods Calcium is a kind of mineral element that we are familiar with but also attaches great importance to, but everyone's understanding of it is still focused on improving bone development, preventing children's rickets, etc., and it is rarely associated with the development of the eye, but medical experts pointed out Calcium deficiency is one of the important causes of poor vision development and even the formation of myopia. The scientific basis is: the eyeball is like a plastic capsule filled with water. If calcium is lacking, its "hydraulic" will flicker and fall, and it can't maintain its normal state. This kind of situation is like a light bulb. It's easy to get burned by the same voltage that is going up and down. If the eyeball lacks calcium, it can cause abnormal development and form myopia. Foods containing calcium are: milk, soy products, fish, animal bones, etc., but also pay attention to the animal's liver, egg yolk, green vegetables and other foods rich in vitamin D, in order to increase calcium absorption and utilization.
