1. Promote the formation of rhodopsin in the eyes: rhodopsin is the most basic substance for the eyes to produce vision, which can enhance the sensitivity to darkness and weak light. It can make the visual field imaging more realistic and improve the night vision ability. Workers who work at night or in front of electronic screens need to consume more anthocyanins.
2, strong antioxidant capacity, effectively scavenging free radicals: Anthocyanin is a flavonoid and a strong antioxidant, which can protect vitamin A from oxidation and increase the content of vitamin A in the retina. It can effectively remove free radicals, reduce the oxidative damage of free radicals to eye lens cells, help the eyeball recover elasticity and slow down the decline of vision. So as to relieve eye vision decline and fatigue, and maintain blurred vision, photophobia, tears, dry eyes and presbyopia.
3, improve vision, prevent myopia: can effectively inhibit enzymes that destroy eye cells, and can prevent myopia, prevent severe myopia and retinal detachment, and improve vision.
4. It has a strong anti-inflammatory effect: anthocyanins can alleviate and alleviate the inflammatory reaction of eyes to a certain extent, such as inflammation damaging lacrimal glands, leading to dry eyes.
5. Enhance blood circulation and protect the regulation of ciliary muscle: it can maintain normal cell connection, stabilize blood vessels, promote microvascular circulation, promote blood flow and stabilize eye blood vessels. It can keep the smaller blood vessels around the reinforcement unobstructed, including the microvessels in the eyes, skin and the whole body.
6. Deliver nutrients to eyes and brain: help nutrients penetrate cells, quickly pass through the brain-blood barrier, and bring nutrients to eyes and brain.
7, to prevent ultraviolet damage: light will enter the lens after passing through the pupil, the lens not only adjusts the focal length, but also absorbs ultraviolet light to prevent ultraviolet light from entering the interior and causing damage. The intake of anthocyanins helps to prevent the lens from being damaged by ultraviolet rays, so it can delay the possibility of lens turbidity and even develop into cataract.
Foods rich in anthocyanins
Anthocyanin is not only a natural pigment, but also a natural health care product.
Anthocyanins are widely found in many main fruits. Foods rich in anthocyanins include blueberries, blackberries, cherries, eggplant, pomegranate, purple rice, black rice, black beans, blueberries, purple potatoes, cherries, medlar, strawberries, grapes, purple corn, rouge radish and purple yam.
Therefore, we should always choose to eat some purple fruits and vegetables to supplement anthocyanins. However, anthocyanin is water-soluble, which can be quickly detected in human blood within 20 minutes after taking it, but it will be metabolized as quickly as vitamin C in the body, so we should supplement some foods containing anthocyanin every day.
Second, besides food, we should also do the following:
Take a reasonable rest, increase outdoor exercise and strengthen eye exercises.
2. Regularly supervise optometry in stereoscopic center. If there is any problem, please handle it in time.
We should wear proper reading glasses, which can slow down the aging of presbyopia.
We should keep happy. Happiness is the source of health.
