It's not about seeing "correctly". No human can see colour perfectly. It's about making it easier to distinguish colours that most people can easily distinguish. If someone came up with a way for me to distinguish more colours, e.g. like a tetrachromat can [1], I'd be keen to try it. My father is red-green colourblind, so I've seen some consequences of it. I consider it a disability (there are ordinary things my dad just can't do), but it doesn't require fixing. To most people red and green are as different as black and white; imagine having trouble distinguishing black and white, and you'll have an idea why some people think you might want these glasses. (Yes, I'm making assumptions about your vision here that might not be correct.) [1] https://en.wikipedia.org/wiki/Tetrachromacy#Humans https://en.wikipedia.org/wiki/Tetrachromacy#Humans
