Contributes to the maintenance of normal vision & protection of cells from oxidative stress.Aging, a bad diet, smoking, and excessive exposure to light all harm our visual cells by releasing free radicals and singlet oxygen. The cell naturally possesses antioxidant systems to defend itself. However, when the free radicals and singlet oxygen levels reach too high, these systems fail and the cell is destroyed. This is known as oxidative stress. This phenomenon causes numerous diseases, including macular degeneration. Naturophta Macula® is a comprehensive formula based on scientific research* on the oxidative stress that causes eye aging.
