Of all the senses, vision may be the most important for participating in our visually oriented world. But some people experience deteriorating vision as they age, with accompanying loss of independence and reduced quality of life. Specific antioxidants can help prevent and even reverse this loss of eyesight.

Lutein and zeaxanthin are carotenoid antioxidants that are concentrated in the eyes, where they protect the lens and retina from damage caused by toxic free radicals and exposure to sunlight. Zeaxanthin supports the macula, the central area of the retina that sees fine detail, while lutein protects the macula and the rest of the retina. Research shows that taking a quality lutein supplement every day can increase optical pigment levels in the retina and prevent or slow the progression of age-related macular degeneration, and cataracts. Lutein also improves visual acuity, glare recovery, and night vision in people with degenerative eye conditions.
