I used this product to remove stubborn protein deposits from my lenses (I wasn't taking care of them properly). My lenses are at least four years old, and they are wearing very well now after using this cleanser. Good support from the company help line--box instructions say to use once per week, but the protein deposits were very stubborn and I was advised I could use the product more often, so after using twice/ week for two weeks, my lenses were as good as new.
