Platinum Naturals Total Vision Care Vegan - A vegan formula that supports eyesight, reduces the risk of developing cataracts, and helps to improve conditions related to eye strain, digital eye burn, night vision, and visual acuity. Uses therapeutic doses of 20 mg of lutein esters and 2.5 mg of zeaxanthin in natural oils extracted from Marigold. Lutein and zeaxanthin protect the macula and photoreceptors in the retina from oxidative stress, as well as helping to filter out high-energy visible blue light.
