Colorful Nutrients from Leafy Greens Support Eye Health
Lutein and zeaxanthin are yellow-orange pigments naturally found in spinach, kale, and corn. They accumulate in the retina, where they act as antioxidants and contribute to the eye's natural defense against light-induced stress. Most people get less than recommended amounts of these nutrients from diet alone, which is why they are often included in eye health supplements.
