Protecting long-term vision requires more than corrective lenses. Nutritional support, particularly from targeted antioxidants, plays a central role in maintaining the health of the eye’s delicate structures. Among these nutrients, lutein and zeaxanthin stand out as two of the most clinically studied carotenoids for vision support. These compounds are naturally concentrated in the retina, where they contribute to optimal macular pigment density and filter harmful light.
What Are Lutein and Zeaxanthin?
Lutein and zeaxanthin are yellow-orange pigments classified as carotenoids. Found in leafy greens, orange peppers, and certain fruits, these nutrients accumulate in the macula, the central part of the retina responsible for high-resolution vision. Their concentration in the macula is up to 10,000 times greater than in the bloodstream.
The body cannot produce lutein and zeaxanthin on its own, making dietary intake or supplementation essential. They are known to protect the eye by acting as antioxidants and by absorbing high-energy blue light that can potentially damage retinal cells.
How Do They Support Eye Health?
Lutein and zeaxanthin play several key roles in supporting visual function:
- Filter high-energy light: These carotenoids absorb blue light and ultraviolet radiation, functioning as “internal sunglasses” that reduce oxidative stress on the retina.
- Support macular pigment density: A denser macular pigment has been associated with improved visual acuity and contrast sensitivity, as well as reduced light scatter and glare.
- Act as antioxidants: By neutralizing reactive oxygen species, lutein and zeaxanthin help maintain the structural integrity of retinal cells.
Research from the AREDS 2 study and other clinical trials supports the use of supplements containing these carotenoids for individuals seeking to maintain healthy vision with age.
Included in the AREDS 2 Formula
The National Eye Institute’s AREDS 2 (Age-Related Eye Disease Study 2) recommended a specific blend of nutrients, including lutein and zeaxanthin, for supporting macular health. VisiVite’s AREDS 2 eye supplements follow this clinically studied formula, offering different variations such as zinc-free or vitamin E-free for individuals with specific sensitivities.
VisiVite formulations feature FloraGLO® Lutein and OmniXan® Zeaxanthin, both derived from natural sources like marigold flowers and paprika. These high-quality ingredients are provided in vegetarian capsules and are free from artificial colors and fillers, supporting nutrient bioavailability and tolerability:contentReference[oaicite:0]{index=0}.
By delivering precise levels of these macular carotenoids, AREDS 2 eye supplements help promote clear vision and protect the retina from oxidative and photic stress over time. Consistent daily use may contribute to maintaining visual function, especially as the eyes age.
