ADVANCED EYE HEALTH SUPPLEMENT*
designed to help maintain long-term eye health and support visual performance.*
THE BENEFITS OF VISIONEX
One important reason for the loss of visual acuity over time is the damage to our eyes caused by environmental factors. Except when we are asleep, our eyes are constantly exposed to environmental elements such as air pollution, dryness, and oxidative damage from sunlight. The ingredients found in Visionex work together to help support healthy vision. The formula is designed to protect the delicate tissues of the eye from photo-oxidation.*
Supplementation with the lutein and zeaxanthin in Visionex can also help preserve visual function. Use of these important carotenoids sustains tolerance to and recovery from exposure to bright light, supports visual acuity in low-light or hazy conditions, and can maintain healthy vision by making edges appear clearer.*
Research also suggests that lutein may be beneficial in maintaining healthy skin.*
THE SCIENCE OF VISIONEX
When light shines through the inner layers of the retina, it is filtered through the yellow pigment of the macula. The macula is especially vulnerable to oxidative damage because it has a high metabolic rate and because the light focused on it encourages the production of free radicals. The yellow pigment helps protect the sensitive receptors in the macula from the potentially harmful effects of short-wavelength light.*
Macular pigment includes the carotenoids lutein and zeaxanthin, an isomer of lutein, which protect eye health in two ways: fi rst as fi lters that absorb some of the high-energy blue light and, second, as antioxidants that quench light induced free radicals and reactive oxygen species.
Average levels of macular pigment tend to be low, especially in those who do not eat many fruits and vegetables. And maintaining an adequate level is important, not only for long-term eye health, but also because macular pigment optical density (MPOD) has been linked to visual performance. Supplementing with lutein and zeaxanthin can help increase MPOD, which helps support visual acuity and maintain long-term eye health and tolerance to glare, contrast, and photostress.*
In addition to lutein and zeaxanthin, the Visionex formulation contains three other important nutritional aids to eye health: bilberry extract, vitamin C, and zinc. The bilberry fruit is rich in antioxidant anthocyanosides and has been shown to help retain healthy capillaries, including those in the eye. Vitamin C provides additional antioxidant protection, especially to the retina, where the concentration of vitamin C is significantly higher than that found in the blood. And zinc appears to provide an additive effect to antioxidants in promoting good visual acuity.*
Lutein and zeaxanthin also offer benefits for skin appearance by increasing surface lipids (good for hydration and elasticity) and enhancing natural antioxidant photo-protective activity to reduce the visible effects of the sun. The vitamin C in Visionex also supports the synthesis of collagen, which is an important structural protein in the skin.*
THE USANA DIFFERENCE
Sun exposure and screen time in front of a computer’s glare can take a toll on your vision. Guard your long-term eye health with proper protection, such as sunglasses, and provide your eyes with the dietary carotenoids they need. The links between lutein and zeaxanthin and eye health are so strong that several national and regional health organizations have recommended an increase of dietary lutein. The amounts of lutein, zeaxanthin, and other eye-supporting nutrients working together in Visionex can help protect the future of your eyesight.*
