Eight kinds of foods to relieve eyesight fatigue and have bright eyes

　　Relieve visual fatigue and eat these eight foods for bright eyes. In recent years, with the development of science and technology, mobile phones, computers and other tools have become extremely common, and they have seriously affected people's vision. Now people's vision problems have become a serious problem. Nowadays, more and more people are suffering from myopia. The first symptoms of myopia are eye fatigue and blurring, which eventually leads to loss of vision and then slowly turns into myopia. If you don’t want your eyes to be with you for the rest of your life, you might as well try eating these foods.

　　1. Wolfberry

　　Lycium barbarum has the effect of nourishing the kidneys, promoting essence, and improving eyesight. Many office workers like to drink wolfberry and chrysanthemum tea to protect their eyes and relieve eye fatigue. The eye-protecting effect of wolfberry depends on the zeaxanthin in it. Eating wolfberry can reduce ultraviolet stimulation and protect the optic nerve from damage.

　　The best and easiest way to take advantage of the eye-protecting effects of wolfberry is to chew it and eat it. Generally, it is appropriate for healthy adults to eat about 20 grams of wolfberry every day. If you chew wolfberry dryly, the amount you eat should be halved, otherwise it is easy to over-nourished.

　　2. Carrot

　　Carrots contain a large amount of carotene, which can be converted into vitamin A in the human body, so it is called provitamin A. Vitamin A plays an important role in the formation of human vision. It participates in the synthesis of rhodopsin in the retina. If vitamin A is insufficient, the eyes' ability to adapt to dark environments will decrease, and in severe cases, night blindness may result.

　　When eating carrots, please note that carotene is a fat-soluble vitamin that needs to be combined with oil to be absorbed by the body, so it must be cooked.

　　3. Pork liver

　　The content of vitamin A in animal liver far exceeds that of milk, eggs, meat, fish and other foods. It has the function of maintaining normal growth and reproductive functions; it can protect the eyes, maintain normal vision, and prevent dry eyes and fatigue.

　　4. Kiwi fruit

　　There is a high content of vitamin C in the lens of the eye, which acts as an antioxidant to protect the eyes. If you are deficient in vitamin C, you are prone to cataracts. The vitamin C content of kiwi ranks very high among many fruits.

　　5. Corn

　　Also because it contains a large amount of lutein and zeaxanthin, it can protect the eyes, has a strong antioxidant effect, absorbs harmful light entering the eyes, and keeps the macular healthy.

　　6. Egg yolk

　　The lutein and zeaxanthin in egg yolk are recognized as nutrients that are good for the eyes. After eating, they can make the eyes brighter. These two types of nutrients can reduce the damage of ultraviolet rays to the eyes, delay the aging of the eyes, and prevent eye diseases such as macular degeneration and cataracts.

　　Some patients with high cholesterol, high blood fat, and high blood pressure should not eat too much at a time. Half an egg yolk to one egg yolk a day is appropriate.

　　7. Kelp

　　In addition to iodine, kelp also contains mannitol. There is a thick layer of "white frost" on the surface of dried kelp. This is the mannitol in kelp. Mannitol has a diuretic effect, can reduce intraocular pressure, and has a good effect in treating acute glaucoma.

　　8. Spinach

　　Rich in potassium, calcium and magnesium, it can help enhance the elasticity of eye muscles and prevent myopia from occurring. It is also a good source of vitamin B2 and beta-carotene. When vitamin B2 is sufficient, the eyes are less likely to become bloodshot; and beta-carotene can be converted into vitamin A in the body to prevent dry eye disease and other symptoms.

　　The above foods can effectively relieve visual fatigue, but to treat the symptoms rather than the root cause, the most important thing is to avoid overuse of the eyes. After using a computer or mobile phone for a long time, you should get up and move around appropriately, and look into the distance. These can help relieve eye discomfort.
