How to improve eyesight?
To improve vision, we must mention the three important nutrients: beta-carotene, lutein and zeaxanthin.
β-carotene: Not only does it promote the formation of endogenous photopigments and enhance vision, β-carotene also helps in the synthesis of rhodopsin in the retina, improving night vision. Common food sources include green leafy vegetables and orange-yellow fruits and vegetables, such as carrots and papayas.
Lutein and zeaxanthin: Urban people stare at electronic screens for a long time, and their retinas are stimulated by blue light for a long time. The blue light penetrates the eyeball directly to the retina and macular area, producing a large number of free radicals, destroying eye cells, and may seriously impair vision. Lutein and zeaxanthin can filter blue light and protect the eyes from blue light damage.
