The nutritional composition of freshwater fish is very high. Many parents will regularly take various freshwater fish in order to ensure that they can immediately supplement the nutritional composition for their children. Many people have specific effects when eating fish eyes. Some people also think that there is a lot of zinc in the fish eyes, which is not suitable for the body to take, These two different views made everyone very confused, so can fish eyes be eaten? Let's have a look.
 First, can fish eyes be eaten? Of course. Scientific research says that eating fish every week can reduce the probability of macular degeneration in both eyes. Naturally, the nutritional composition of fish eyes need not be exaggerated. Zhang Zongduan, chief physician of the Department of Traditional Chinese Medicine Ophthalmology in the outpatient department of the Optometry Hospital attached to Wenzhou Medical College in Zhejiang Province, stressed that although there are collagen powder and unsaturated fat in the fish eye, its composition is not higher than that in other parts of the fish.
 Secondly, for both eyes, we should also pay attention to the supplementation of vitamin D, carotene, protein and other trace elements with strong antioxidant capacity. They are essential substances to participate in activities such as fundus macular metabolism, melanin epithelial cell biochemistry, and fish eyes do not contain these elements. In other words, eating fish eyes may not be about nutrition, but just as a kind of etiquette knowledge for drinking. Many areas will have such customs and habits. The owner selects one fish eye from the chopsticks and puts it into the goblet of the noble customer. The customer must drink the cup full, which means to look high.
 Third, eating fish is good for clearing eyes. Because fish body contains rich and colorful carbohydrates, unsaturated fats, etc., it has the effect of maintaining eye tissue. The middle-aged and old people eat more fish, which is conducive to preventing retinal degeneration and fundus diseases in the elderly. This symptom is often the key reason for the decline of eye vision and blindness in the middle-aged and elderly. However, scientific research has found that eating fish can protect your eyesight, but eating too much is harmful to your eyes. When the fish consumption reaches a certain level, the effect of preventing retinal degeneration will not increase but decrease.
 Can fish eyes be eaten? Yes, from the perspective of vision protection, authoritative experts suggest that people should also often take vegetables, fruits, fresh fruits and various coarse grains to supplement nutrients beneficial to the eyes in an all-round way. Vegetables and fruits with strong antioxidant capacity, high photosynthetic intensity, high vitamin C and high methyl cellulose, such as betel vegetables, broccoli and other dark brown vegetables, as well as peppers, tomatoes, towel gourds, turnips and sweet potatoes, should be used more frequently.
