Higher Nature Visual Eyes is a potent supplement packed with antioxidants which can help to fight off oxidative damage to the eyes. In order for us to be able to see correctly, our eyes need light. However, light could cause free radical damage to our eyes if they are not protected. Air pollution, poor diet, alcohol and smoking can also cause free radical damage to the delicate cells in our eyes. An adequate intake of meso-zeaxanthin and zeaxanthin is recommended by opticians in order to best try to maintain sharp vision and healthy eyes, and these are included in this formula alongside lutein, vitamins A, B2, C and zinc which help to maintain vision, as well as Bilberry extract and vegan DHA.
