Researchers at Missouri University of Science and Technology are studying eye drops prepared with the antioxidant N-acetylcysteine amide (NACA) as a treatment for these eye conditions. NACA is an improvement over another experimental treatment, theantioxidant N-acetylcysteine (NAC), because it passes more easily across cell membranes, allowing the medication to be used in lower doses. NACA is also an excellent source of glutathione, a cell's main antioxidant power, which is diminished during degenerative eye disorders.To see more details visit, www.healthcanal.com
