When it comes to protecting eyes and vision, most people think of vitamin A. In fact, there are many nutrients that are also closely related to eye development, prevention of tissue aging, and maintenance of optic nerve health. For example, vitamin B complex, vitamin C, carotene, DHA, etc. are all good nutritional supplement options!
1. Vitamin A
Foods containing vitamin A and carotene are good for the eyes. Because vitamin A (which can also be converted from carotene) is an essential component for mucosal cell fractionation, if the mucus secretion is insufficient, the eyes are prone to dry eyes such as dryness, fatigue, and hyperemia; in addition, vitamin A is also intracellular rhodopsin (It is a kind of pigment-protein that can accept light stimulation). If rhodopsin cannot be formed, the ability of the eyeball to adapt to the dark environment will decrease, and night blindness is prone to occur in severe cases.
2. Vitamin B complex
Such rich vitality factors are contained in animal liver, milk, lean meat, green leafy vegetables, beans, wheat germ, brown rice, and brewer’s yeast.
3. Vitamin C
Vitamin C is an anti-oxidant substance and one of the components that make up the eye lens. In addition to preventing aging of the lens and avoiding UV damage to the retina, it also promotes the formation of collagen, increases the toughness of the small blood vessels in the eye, and helps improve eye health. If the body lacks vitamin C, cataracts with cloudy crystals are prone to occur.
However, vitamin C cannot be synthesized by the body on its own and needs to be taken from food every day. Therefore, it is recommended that you choose more dark green and yellow-red fruits and vegetables rich in vitamin C in your diets, such as green peppers, cucumbers, cauliflower, cabbage, fresh dates, guava, tomatoes, strawberries, kiwi, grapefruit, and other fruits and vegetables.
4. DHA
When it comes to DHA, I believe most parents will say: “This is important nutrition that can help babies grow up intelligently…” But you may not know that DHA is also a component of the eyeball! This essential fatty acid, which the human body cannot produce, belongs to omega-3 polyunsaturated fatty acids. DHA accounts for about 40% to 50% of retinal phospholipids (mainly concentrated in the retina and photoreceptors).
Since DHA can pass through the Blood Ret in a Barrier, it can stimulate the photoreceptor cells on the retina, so that the information can be quickly transmitted to the brain and achieve the effect of visual enhancement. It is recommended that you choose more DHA-rich seaweed foods and deep-sea fish, such as salmon, tuna, etc.
