I always come back to the analogy of nearsightedness. You can be a little bit nearsighted, or a lot nearsighted. It’s a continuum. It isn’t even precisely a problem to be nearsighted, in theory. It’s just a problem in our society which is designed around being able to see things that are far away (e.g. road signs.) Glasses aren’t technically a treatment for an illness; they’re an optional prosthesis—a “body mod” in the cyberpunk sense. But there’s no stigma to getting them (nor should there be); and anyone who has any degree of nearsightedness has no reason not to get them.
