I'm highly red/green colorblind. I got a pair of these as a gift and they allow me to differentiate between reds/greens much more clearly and to see red where I wouldn't notice without them. I know for some people they don't do much, but it makes hikes and such much more colorful for me!

I can't speak for OP's colorblindness, but for me those do basically nothing.

This company has so shady marketing. They don't work as advertised.

The way they hire actors to play out wholesome videos and upload them to YouTube as if it's organic content, with massive fake users to comment and push up false claims and down vote brigade all negative comments should tell you all you need about this shady company.
