Key Nutrients in Eye Health

Healthy eyes depend on normal nutrition, but that does not mean more of every “eye nutrient” is better. Context, deficiency risk, diet and clinical indication matter.

Commonly discussed nutrients

Lutein and zeaxanthin are carotenoids associated with macular pigment. Vitamins C and E, zinc and copper are components of the AREDS2 formulation at specific doses. Vitamin A is essential to normal visual function, but excess supplementation can be harmful.

For product decisions, move from this overview to vision supplement categories, not directly from a nutrient name to a purchase.
