After 6 months, 90% of NAC-treated eyes showed improvement in best corrected visual acuity (7 to 100%) and 88.9% showed a 27 to 100% improvement in glare sensitivity.

Is carnosine good for eyes?

The protein, L-carnosine, is known to have an antioxidant effect on the cataractous lens, so biochemically there is sound logic for exploring L-carnosine as an agent to reverse or even prevent progression of cataract. When applied as an eye drop, L-carnosine cannot penetrate the eye.

What does carnosine do for the eyes?

L-carnosine, a product of N-acetyl L-carnosine, can pass through the aqueous and lipid components of the eye, preventing DNA strand breaks caused by UV damage. Cataracts form with the cross-linking of lens proteins caused by free radicals, which are produced during UV exposure over time.
