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, cataracts, glaucoma, and diabetic retinopathy. Lutein also improves visual acuity, glare recovery, and night vision in people with degenerative eye conditions.
Natural Factors Lutein is ideal for anyone experiencing or wanting to prevent degenerative vision loss. It contains LuteinRich™, pure, high potency lutein and zeaxanthin derived from marigold petals. LuteinRich is non-irradiated and GMO-free. Try this high-quality form of lutein to support optimal eye health.
Lutein and zeaxanthin are antioxidants that protect the retina of the eye. The retina is a multi-layered tissue structure that lines the back of the eye. It contains millions of cells that capture light rays and convert them into electrical impulses. These impulses travel along the optic nerve to the brain where they are turned into images.
Zeaxanthin is especially important in protecting the macula, the central area of the retina which is responsible for the precise, detailed central vision that allows us to perform tasks such as reading. Zeaxanthin is highly concentrated in the central part of the macula, called the fovea, and decreases further out into the macula, where lutein is concentrated.
The protective effect is due in part to preventing oxidative damage caused by toxic free radicals. Some experts believe that the orange pigment of lutein also protects the eyes by filtering the damaging rays of blue light and near-ultraviolet radiation from indoor lighting and sunlight. The more unfiltered sunlight that reaches the eyes, the more lutein is needed to defend delicate retinal tissues. The body can convert lutein into the proper amount of zeaxanthin it needs. This makes lutein the key carotenoid for ensuring optimal amounts of both lutein and zeaxanthin.
