This formula provides antioxidant support as well as key nutrients to help maintain the long-term health of the eyes. In the US, eye health is a common concern for those over 60 years of age. The eye is the most susceptible organ to oxidative damage caused by light, toxins, atmospheric oxygen and abrasion. As ultraviolet and blue light pass through the retina to the photoreceptors (rods and cones) and the pigmented epithelial cells, reactive oxygen species (free radicals) are generated. If there are insufficient antioxidants available to neutralize free radicals, the eye undergoes excessive oxidative damage.
