Vizion Edge is a patented formula made of the three carotenoids [a fancy word for nutrients] found in your eyes' retina. These carotenoids are called lutein, zeaxanthin, and meso-zeaxanthin. Lost yet? Don’t worry, we’re here to simplify for you. Basically these three nutrients have major antioxidant properties to protect your eyes from dangerous free radicals, oxidative stress, and harmful blue light — All of which leads to loss of visual acuity. By rebuilding and maximizing these nutrients with Vizion Edge, vision becomes sharper, clearer and all around enhanced no matter your surroundings. This means even with poor weather conditions, low lighting, or glare you won’t be thrown off your game. Vizion Edge is an all-natural, patented formula certified by Informed Sport and NSF.
