How to improve eyesight?

To improve eyesight, you must mention three important nutrients: beta-carotene, lutein, and zeaxanthin.

Beta-carotene: Not only does it promote the formation of photosensitive pigments and enhance vision, beta-carotene also helps synthesize rhodopsin in the retina, improving night vision. Common food sources include leafy green vegetables and orange-yellow fruits and vegetables, such as carrots and papayas.

Lutein and Zeaxanthin: Urban dwellers spend long hours staring at electronic screens, exposing their retina to prolonged blue light stimulation. This blue light penetrates the eyeball, reaching the retina and macula, generating numerous free radicals that damage eye cells and can severely impair vision. Lutein and zeaxanthin both filter blue light, protecting the eyes from its harmful effects.
