How to improve vision?
To improve eyesight, we must mention the three important nutrients of β-carotene, lutein and zeaxanthin.
β-carotene: not only promotes the formation of photosensitive pigments and enhances vision, β-carotene also helps the synthesis of rhodopsin on the retina and improves night vision. Common food sources include green leafy vegetables and orange-yellow fruits and vegetables, such as carrots , papaya, etc.
Lutein and zeaxanthin: Urbanites stare at electronic product screens for a long time, and the retina is stimulated by blue light for a long time. The blue light penetrates the eyeball and reaches the retina and macular area, generating a large number of free radicals, damaging eyeball cells, and seriously damaging vision. Lutein and zeaxanthin have the effect of filtering blue light, which can protect the eyes from blue light.
