- An antioxidant formula designed to help support healthy eyes
- Reduces the risk of cataracts and age-related macular degeneration
- Powerful eye antioxidants that support eye health.
Care For Your Eyes with Lutein
As we age, there is a general decline in our acuity of vision, but this doesn’t have to be an inevitable part of growing older. Maintain healthy vision with USANA’s Visionex. This comprehensive formula is designed to maintain long-term eye health with two of the most powerful free-radical fighting antioxidants; lutein and zeaxanthin.
Because our eyes are constantly exposed to harsh environmental factors such as air pollution, dryness, and oxidative damage from sunlight, the extra health maintenance you’ll get from USANA Visionex will go a long away toward maintaining your healthy vision.
• A unique and comprehensive formulation of ingredients to maintain good eye health
• Guaranteed levels of lutein and zeaxanthin, important antioxidant components of the macula of the eye
• Includes vitamin C, bilberry extract, and zinc for additional support in the maintenance of healthy eyes
• Visionex is laboratory tested, quality guaranteed. Meets British Pharmacopoeia (BP) specifications for potency, uniformity and disintegration where applicable.
USANA Visionex – Were You Aware?
Ophthalmologists recommend adding lutein and zeaxanthin to your daily diet to help maintain long-term eye health.
Your eyes are your window to the world. Outside of good health itself, nothing is more precious than the gift of sight. Everyone sees differently, in part due to differences in the acuity of our vision and the general state of our health, but we owe it to ourselves to do everything we can to maintain optimal vision.
As we age, there is a general decline in acuity of vision. One of the most important reasons for the loss of visual acuity over time is the damage caused by environmental factors. The eyes are not sequestered inside the body as the heart or kidneys are. Except when we are asleep, our eyes are constantly exposed to environmental factors such as air pollution, dryness, and oxidative damage from sunlight.
There are things that we can do to retain eye health. Firstly, we can reduce the amount of damaging environmental effects we subject our eyes to each day. For example, we can minimize exposure to harsh sunlight with quality sunglasses, especially while driving, and if we work at a computer terminal for long periods, breaks of just a minute or two of looking at distant objects can reduce eye strain significantly.
Secondly, today’s lifestyles and working conditions result in ever-increasing demand for defense from oxidative damage. We can help to retain proper functioning of our eyes by providing nutritional supplementation, especially antioxidants, to counter free-radical damage.
The comprehensive formulation of Visionex is designed to support long-term eye health, especially when combined with preventive measures against exposure of the eyes to harmful environmental influences.

What we actually see with the eye are the patterns of light that strike the retina, a light-sensitive layer of cells at the back of the eye. In the centre of the retina is the macula, where the light rays are most highly focused and visual acuity is highest. The macula is especially vulnerable to oxidative damage because it has a high metabolic rate. Therefore, the energetic radiation (short wavelength light) focused on it enhances the production of free radicals.
The central portion of the retina contains a yellow pigment called the macular pigment. This helps protect the sensitive receptors in the retina, particularly from the potentially harmful effects of blue light. Our eyes receive support from the antioxidant carotenoids that make up the macular pigment – lutein and zeaxanthin.
While the roles lutein and zeaxanthin play in the physiology of the eye are not completely known, the links between lutein and eye health are so strong that several national and regional health organizations have recommended the increase of dietary lutein. Lutein is believed to function in two ways: first as a filter of high-energy blue light, and second as an antioxidant that quenches light-induced free radicals and reactive oxygen species.
Zeaxanthin, a yellow carotenoid, is a modified form of lutein. In the eye, lutein is predominant in the periphery of the macula while the concentration of zeaxanthin is greatest in the very centre. This is where conditions most favour the formation of free radicals. Zeaxanthin is thought to be an even more powerful antioxidant than lutein.
Preserve Your Visual Function
Macular pigment optical density (MPOD) levels have been linked to eye health. Daily lutein and zeaxanthin supplementation has been shown to significantly increase MPOD to help preserve visual function. Use of these important carotenoids improves visual performance in glare (better tolerance to bright light and quicker recovery from photostress), visual acuity in low-light conditions, and most measures of quality of vision (contrast sensitivity), for most subjects.
Why take USANA Visionex?
In addition to lutein and zeaxanthin, the Visionex formulation contains these three important nutritional aids to eye health: bilberry extract, vitamin C, and zinc. The bilberry fruit is rich in antioxidant anthocyanosides. Vitamin C provides additional antioxidant protection, especially to the lens of the eye, where the concentration of vitamin C in the lens is 20 times that found in the blood.
Zinc appears to provide an additive effect to antioxidants in promoting good visual acuity.
Note: Dosage is different from country to country however the active ingredients in this product are the same and is spread over the course of the day.
