We often hear people say that eating more blueberries is good for eyesight, which can relieve eye fatigue and improve eyesight. There is also a little story about the benefits of blueberries.

    According to legend, lishizhen, a famous doctor, suffered from eye diseases when she was young. She felt astringent eyes and could not see clearly. Later, it was discovered in tartar (now northern Mongolia) that the blue berries (blueberries) whose roots grew in the perennial frozen layer had a miraculous effect. Lishizhen often ate them. In her later years, she was still able to see and hear clearly. She told the local Oroqen people that it would be good to eat more. The Oroqen people have become a group of people with good eyesight and are very adapted to the perennial hunting life. Lishizhen specially collected this good medicine for moistening the eyes in the compendium of Materia Medica, which has been passed down to this day.

    So why are blueberries good for your eyes?

    That's because blueberries are rich in anthocyaninsCyanidin Chloride ）. Medical clinical reports show that anthocyanins in blueberries can promote the regeneration of rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and improve vision. Anthocyanins can improve vision in dim light; This is helpful for night drivers, people who stare at the screen for a long time, etc. The reason why anthocyanins are beneficial to the eyes has attracted extensive research by scientists is that during World War II, Royal Air Force pilots were given a diet containing blueberries before conducting night bombing missions. Studies have shown that anthocyanins in blueberries can accelerate the regeneration of "rhodopsin" to promote visual acuity, which is a great help for pilots who often need visual flight and have very strict visual requirements.

    Anthocyanins are powerful antioxidants, which can maintain normal cell connections, stabilize blood vessels, enhance microvascular circulation, and improve the flow of microvessels and veins. There are more than 15 anthocyanins in the mature purple black berries of blueberries, which can effectively inhibit the enzymes that destroy eye cells, which also explains why blueberries are beneficial to eye health.
