An adequate intake of vitamins, minerals, and essential fatty acids, especially vitamin-c, vitamin-e, vitamin-a, zinc, and omega-3 fatty acids, is crucial for eye health.[1] Vitamin A deficiency leads to night blindness and eventually permanent blindness, if left untreated. The carotenoids lutein and zeaxanthin also support optimal eye health.
Dietary patterns rich in fruit-and-vegetable (especially dark leafy greens and yellow- and orange-colored fruits and vegetables), fatty fish, nuts, and legumes are generally associated with a reduced risk of eye disease.[2]
