I have not tried these glasses. I would not pay that much for them.

What I have found is that inexpensive mirrored “fishing” sunglasses make certain colors much more noticeable for me, especially from a distance. The orange or green mirrored lenses seem to do the trick.

It was an accidental discovery on my part. I bought a “cheap” $20USD pair of polarized fishing sunglasses one year before going on a trip to the mountains in the fall (when leaves change color). Other people can easily distinguish red trees way off in the distance, I couldn’t. But when I had the polarized fishing sunglasses on, suddenly I could very easily distinguish between red trees versus the ones that were brown, dead, or leafless. It was fascinating.

It also works in the spring on newly emerging buds, which are often red or pink in color. From a distance, I can’t really see that. But with the glasses on, I could see the red trees from miles away.

So, for $20 it’s a cool novelty to have some of my color vision “restored”. But for the ridiculous cost of these “color blind glasses”, it would not be worth it to me.
