Can eating blueberries regularly prevent high myopia?

Generally speaking, regularly consuming blueberries can help prevent severe myopia, as they have a certain positive effect in preventing severe myopia. The detailed explanation is as follows:

Blueberries are rich in anthocyanins, which are potent antioxidants. Anthocyanins can promote the regeneration of rhodopsin in retinal cells, helping to protect vision. At the same time, they can also help the eyes adjust to light and improve night vision. Moreover, blueberries are rich in vitamin A, an essential nutrient for maintaining eye health. Vitamin A helps promote the development of eye nerves, thereby improving vision.

The combined effects of anthocyanins, vitamin A, and other components in blueberries can effectively protect vision and prevent vision deterioration. Consuming blueberries in moderation can help prevent myopia to some extent and may even enhance visual acuity. This is because the nutrients in blueberries nourish the optic nerves and retina. Additionally, prolonged use of the eyes can cause visual fatigue, but the nutrients in blueberries can alleviate this fatigue and make the eyes feel more comfortable.

Although regularly consuming blueberries has a positive role in preventing severe myopia, one should not rely solely on blueberries for myopia prevention. It is important to maintain good eye habits in daily life, avoid prolonged near-eye work, and periodically look into the distance to relax the eyes. Regular eye examinations should also be conducted to detect and address vision problems promptly.
