In the retina of the human eye, there is a purple pigment called rhodopsin, whose function is to transmit light stimulation to the brain and make people feel that they have seen something. The important function of anthocyanin pigment in blueberry is to promote the biosynthesis of retinol, thus enhancing people's vision.
Anthocyanin is an active substance and an important element to maintain eye health and prevent visual impairment. Its function is to protect the microvessels of the eyes, thus promoting blood circulation, and at the same time, it has the ability to accelerate the regeneration of rhodopsin, which is indispensable for good vision.
When people's eyes are working, rhodopsin will be decomposed bit by bit by light, and the decomposition speed will accelerate with the growth of age, which will lead to the gradual decline of our vision. Anthocyanins in blueberries can promote the regeneration of rhodopsin in retinal cells.
Anthocyanins can protect vision by inhibiting the apoptosis of photoreceptor cells damaged by photochemical damage of retina. Anthocyanins can protect retina from light-induced retinopathy through preventive neuroprotection.
Anthocyanins in blueberries can improve vision in dim light; This is helpful for drivers at night, people who stare at the screen for a long time, etc.

Eating blueberries helps diabetics to regulate their blood sugar levels. Eating 5 servings of low glycemic index fruits such as blueberries every week for two months can significantly improve the ability of blood sugar regulation.
8. Strong bones
Blueberries are rich in trace element manganese, which plays a key role in bone development. The study found that children who like blueberries have higher bone density than those who don't.
9. Prevention of cancer
