Zeaxanthin is a carotenoid, a type of pigment found in various fruits and vegetables, particularly in leafy greens like spinach and kale. It plays a crucial role in eye health by filtering harmful blue light and protecting the retina from oxidative damage. This compound is often associated with reducing the risk of age-related macular degeneration (AMD) and cataracts. Zeaxanthin works alongside another carotenoid, lutein, to enhance visual performance and overall eye function, making it an important nutrient for maintaining good eyesight as we age.
