I think the main issue is that people expect a magic fix. This is a common problem in the world today. Many things are massively overhyped and then turn out to be a huge disappointment to many people because they are not as perfect as the hype lead them to belive.
I belive these glasses can be a useful tool to some one that struggles with color blindness. But just that. A tool. Not a fix. By understand what these glasses can actualy do and their limitations someone with color blindness can potentially get a lot more information what the hues and colors they wouod normally struggle with. They won’t however maks them suddenly see in perfect color.
I hope they help your wife, and I belive that if she uses them as an aid, not a fix, they will help her a lot.
Best of luck.
