Blueberry has the effect of improving vision. At the same time, the blue pigment-anthocyanin contained in blueberry has the function of promoting micro-circulation of blood in the eye and maintaining normal intraocular pressure.
Blueberry contains the carotene, which has a great effect on protecting vision. Carotene is a photosensitive substance in visual cells, which can be converted into vitamin A in human body, and can treat night blindness, dry eye disease and epithelial keratosis.
All the nutrients in the blueberry are needed by the eyes. For example, anthocyanins, carotene and lutein have an important influence on vision protection. These nutrients account for a relatively high proportion in blueberries, so it is better to eat more blueberries.
