Eyes require many important “vision factors” to stay healthy. They require good blood flow and normal blood pressure to assure a steady supply of oxygen and essential nutrients to all parts of the eyes including the retina and optic nerve. Eyes also need lots of antioxidant protection to prevent vision deterioration and loss.
According to the latest eye research, the eye's lens, iris and cornea require
vitamins C and E, lutein and zeaxanthin, together with zinc, copper and selenium to protect against oxidative damage from UV and blue light and other oxidants that can cause cataracts. A healthy retina including the macula (central retina) and the fovea (central macula) requires carotenoids lutein, zeaxanthin and lycopene. These "phytochemical" nutrients help increase pigment density in the retina and protect it against light damage.
Vitamins B, C and E, and zinc, copper and selenium, are needed for retinal function and zinc is vital for metabolism in the retina and for night vision. Bilberry and blueberry anthocyanins increase the production of certain pigments needed for night vision.
The Vision Factors formula includes a broad range of these healing and protective nutrients from wholesome vegetables, fruit and berries: colourful blue and purple flavonoids from bilberries and blueberries;lutein and zeaxanthin to protect the lens and retina against light and oxidative damage; red lycopene from tomatoes, a powerhouse antioxidant; and the antioxidants
CoQ10, vitamins C and E; as well as B vitamins, zinc, selenium and copper, all nutrients shown to be important for eye health.
