If you want to protect your eyes, eat these 8 kinds of food regularly!

As more and more people are suffering from myopia, people's awareness of eye care is also increasing. In order to protect the eyes, in addition to paying attention to daily life, you can also eat some eye-nourishing foods regularly.

1. Carrots

Carrots are the most famous eye-protecting food. They contain a lot of carotene, which can be converted into vitamin A in the human body, so they are called provitamin A. Vitamin A plays an important role in the formation of human vision. It is involved in the synthesis of rhodopsin in the retina. If there is a lack of vitamin A, the eye's ability to adapt to dark environments will decrease, and in severe cases it may lead to night blindness.

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

2. Egg yolk

The lutein and zeaxanthin in egg yolks are recognized as good nutrients for the eyes, and eating them can make your 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 retinal macular degeneration and cataracts.

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

3. Kelp

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

4. Corn

Because corn contains a large amount of lutein and zeaxanthin, it has a powerful antioxidant effect. It can absorb harmful light entering the eyes and keep the macula healthy.

5. Spinach

Spinach is rich in potassium, calcium and magnesium, which can help increase the elasticity of eye muscles and reduce the risk of myopia. It is also a good source of vitamin B2 and beta-carotene. When there is sufficient vitamin B2, the eyes will not easily become bloodshot; and beta-carotene can be converted into vitamin A in the body to prevent dry eye disease and other symptoms.

6. Kiwi

The lens of the eye contains a high content of vitamin C, which acts as an antioxidant to protect the eyes. If you lack vitamin C, you are prone to cataracts. The vitamin C content of kiwifruit ranks very high among many fruits.

7. Wolfberry

"Compendium of Materia Medica" records: "Goji berries can nourish the kidneys and produce essence, nourish the liver and improve eyesight." The eye-protecting effect of goji berries also depends on the lutein contained in them. Eating wolfberry can reduce ultraviolet stimulation and protect the optic nerve from damage.

If you want to maximize the eye-protecting effect of wolfberry, the best and simplest way is to chew it and eat it. It is suitable for healthy adults to eat about 20 grams of wolfberry per day. If you chew wolfberries dry, you should halve the amount you eat, otherwise you may over-nourish yourself.

8. Pork liver

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