Both adults and children are exposed to blue light-emitting electronic products such as mobile phones, computers, tablets, and TVs every day. Since this bad blue light can harm our eyes, we must supplement our eyes with good nutrients to maintain healthy vision.
Vitamin A
If you feel your eyes dry and feel dizziness at night or loss of vision, you are probably lacking vitamins. You can take vitamin A, but vitamin A penetrates tissues where there are fat cells, such as the heart, liver, and skin, so try not to take too much. You can take beta-carotene instead of vitamin A because beta-carotene is converted into vitamin A when it enters the body, which can be ingested from green vegetables such as carrots or spinach.
Anthocyanin
When it comes to anthocyanins, the fruit that comes to mind is blueberries. Blueberries are rich in anthocyanins, which are a kind of polyphenol and have a strong antioxidant effect. It has the effect of preventing cataracts, presbyopia, promoting blood flow in the blood vessels of the eyes, relieving muscle tension, and stabilizing fatigue.
Lutein
Lutein is also a kind of carotene, which maintains the density of macular pigment to help maintain healthy eyes. You don’t need to take too much, about 10 to 20 mg a day, because too much intake will temporarily turn the skin yellow, so intake of lutein is good.
Astaxanthin
Astaxanthin is also a kind of carotene, which can help increase retinal blood flow, restore fatigue caused by eye tension, promote eye focus function, and prevent cataracts. Its antioxidant capacity is 550 to 1000 times more than vitamin E! You can get astaxanthin from redfish or shellfish such as salmon, salmon eggs, shrimp, and crab. The daily intake is 4 to 12 mg.
Zeaxanthin
Zeaxanthin is one of the very important substances in the macula of the retina and one of the components of carotene. Zeaxanthin helps prevent vision loss caused by aging, and also reduces the risk of cataracts.
If you want to have good eyesight, the above nutrients are indispensable.
