In the previous article, we discussed “How To Choose The Best Sunglasses For Men”. In this article, let’s talk about “Best Food For Eyesight Improvement”.
The eye is the window of the soul. Like the whole body, it needs to be balanced and nourished as a whole. How to make our eyes bright? We must provide them with essential nutrients. On weekdays, you should adequately take in vitamins A, B1, B2, C and other substances that are helpful to your eyes, and pay attention to nutritional balance. Vitamins are particularly effective in treating dry eyeballs and can give the eyes the nutrients they need.
Water
The transparent cornea is most afraid of dryness. The tears secreted by the lacrimal gland play a role in moisturizing the cornea, and the lens is also immersed in water. In fact, the water maintains the lack of circulation and metabolism in the eye. Lack of water will lead to dry eye, conjunctivitis, keratitis, dacryocystitis, and even cataracts. Therefore, both young and old people should develop the habit of drinking more water to prevent dehydration caused by diarrhea, vomiting, and excessive sweating, so that the eyes can be properly maintained and moisturized, which can improve dry eyes.
Protein and Vitamin A
The cornea, morphology and retina of the eyeball require protein and vitamin A, which can cause cataracts, night blindness and corneal disease when lacking. To develop the habit of eating lean meat, fish, and eggs, vegetarians should supplement milk and soy products because they are rich in high-quality protein. Eat animal liver, carrots, garlic sprouts, coriander, rape, spinach and other foods rich in vitamin A.(https://www.koalaeye.com/collections/eyeglasses)
Vitamin C
The content of vitamin C in human eyes is 30 times higher than that in blood. With age, the content of vitamin C decreases significantly and the lens becomes malnourished. Over time, it causes lens degeneration. Vitamin C can reduce the damage to the lens caused by oxygen in the light, and has the effect of preventing the formation of senile cataracts. Vegetables and fruits are rich in vitamin C, so eat more.
B vitamins
B vitamins are important substances that participate in the metabolism of nerve cells including the optic nerve, and protect the eyelids, conjunctiva and cornea. When lacking or insufficient, it is easy to cause dry eyes, conjunctival hyperemia, eyelid inflammation, photophobia, blurred vision, visual fatigue, and even optic nerve inflammation. Foods rich in B vitamins include peanuts, beans, millet, animal offal, meat, and eggs. Species, fish, rice bran, peas, etc. In addition, vegans need to eat more soy milk or supplement vitamin B.
Calcium
Calcium is the "messenger" in nerves and participates in all kinds of nerve impulses. Nerve cells (including the optic nerve) lack calcium, prone to visual fatigue and distraction.
Zinc
Zinc can enhance the sensitivity of the optic nerve, and zinc deficiency will affect the absorption of vitamin A in the body.
Selenium
Among the various tissue cells of the human body, the eye has the highest selenium content, which is an important trace element for maintaining eyesight.
Foods for eye health
1.Spinach
According to a survey in the United States, eating a lot of spinach can reduce the risk of blindness in old age. A research team from Harvard Medical School pointed out that people who eat a lot of these vegetables every day can reduce the chance of suffering from macular degeneration by 43%.
2.Tomato
Tomatoes are very nutritious. Each catty contains 2-8 grams of protein, 1.4 grams of fat, 9 grams of carbohydrates, 300 mg of calcium, 174 mg of phosphorus, 2 mg of iron, and vitamins A, B1, and B2, C, P, PP, etc. In addition, it also contains fruit acid, citric acid, and lycopene. The content of vitamin PP is the first among fruits and vegetables.
3.Carrot
Carrots have two characteristics. One is that the sugar content is higher than that of ordinary vegetables, and it has an aromatic and sweet taste. The other is that it is rich in carotene, which can be converted into vitamin A when involved in the human body. Vitamin A can protect the eyes and skin. The health of people suffering from rough skin diseases, night blindness, xerophthalmia, and pediatric rickets is because of the lack of vitamin A, especially children who need it more during the developmental period.
