Introduction: As the number of people with nearsightedness continues to rise, patients often experience blurred vision. In severe cases, it can be as debilitating as blindness. So, how can we prevent nearsightedness? And what foods are good for it? The following introduces several foods; let's take a look.
1. Foods High in Protein
In terms of the sclera, it forms the tough outer shell of the eye due to its content of various essential amino acids, which create very strong fibrous tissue. Although the sclera has a certain degree of toughness, it remains relatively weak in the anterior-posterior axis of the eye. Animal-based foods such as meat, fish, eggs, and milk are not only rich in protein but also contain all the essential amino acids.

2. Foods Rich in Zinc
Patients with nearsightedness often show a significant deficiency of two substances: chromium and zinc. Therefore, nearsighted patients can usually consume more zinc-rich foods, such as meat, soybeans, yellow croaker, almonds, seaweed, milk powder, kelp, liver, lamb, and other foods that are relatively high in both zinc and chromium.
3. Foods High in Calcium
Calcium is the main component of bones and also a primary component of the sclera. A higher calcium content plays a major role in enhancing the toughness of the sclera. Animal bones such as cow, pig, and sheep bones are rich in calcium and are easily absorbed and utilized by the body. Other foods like dairy products, soy products, dried shrimp, shrimp eggs, eggs, rape, bok choy, peanuts, and red dates also contain significant amounts of calcium.

5. Foods Rich in Vitamins
Vitamins are essential nutrients for the human body. Although the body's demand for them is small, they play an extremely important role in the body's material and energy metabolism. When using diet therapy to treat nearsightedness, one should appropriately supplement vitamins A, B1, B2, C, and E. Foods rich in vitamins include eggs, milk, meat, fish, liver, and fresh vegetables and fruits.
