To improve eyesight, we must mention the three important nutrients of β-carotene, lutein and zeaxanthin.
Beta-carotene: It does not promote the formation of internal photosensitive pigments and enhance eyesight. Beta-carotene helps the synthesis of rhodopsin on the retina, improves night vision, and prevents night blindness. Common food sources include green leafy vegetables and orange-yellow fruits and vegetables. Such as carrots, papaya, etc.
Lutein and zeaxanthin: Urban people’s eyes have been watching electronic product screens for a long time. The retina is stimulated by blue light for a long time. The blue light penetrates the eyeball directly to the retina and macular area, producing a lot of free radicals, destroying eyeball cells, and causing cataracts and macular disease Serious damage to eyesight. Lutein and zeaxanthin have the effect of filtering blue light, which can protect the eyes from blue light.
