N-Acetyl Carnosine drops for lubrication of the eyes and used as part of the control of cataracts. Cataracts are caused by the hardening and discoloration of the lens due to lifelong cross-linking (glycosylation) of the lens proteins with ascorbate. This persists in the aqueous humor at high concentrations, due to the low availability of natural defences in the form of antioxidants (which decline with advancing age). N-acetylcarnosine delivers L-carnosine into the aqueous humor of the eye (the fluid area surrounding the lens) where it acts as a natural and comprehensive antioxidant, protecting structural lens proteins from the free-radical induced oxidation process. As cataracts develops, antioxidant defence in the body is exhausted, leading to the cross-linking of the lens crystallins and producing a clouded lens and impaired eyesight. The clinical trials show that the regular use of a 1% N-acetylcarnosine (N.A.C.) eye-drop, delivers a high dose of carnosine capable of reversing the lens cross-linking of the lens crystallins and aids in the reduction and possible eradication of cataracts.
