Jonas, here is a link to one study on Can-C Eye Drops: N-Acetylcarnosine sustained drug delivery eye drops to control the signs of ageless vision: Glare sensitivity, cataract amelioration and quality of vision currently available treatment for the challenging 50,000-patient population - PMC
- The study was planned, organized, and supported by Innovative Vision Products, Inc. (IVP), a company based in Delaware, USA, that holds the worldwide patent for the NAC eye drop formulation used in the study. IVP is described as a pharmaceutical/nanotechnology company focused on ophthalmic products.
The study was favorable, but had small numbers of participants. So, I don’t have great confidence in it. In fact, I think it’s a worthless product, but that is just one person’s opinion. From my experience of using these eye drops for 6 months several years ago, I noticed nothing except a thinner wallet. But, they may work for you.
I bought from Amazon years ago, but no longer see the product listed there. Here are two websites that I know nothing about that list Can-C Eye Drops if you want to pursue this:
