@XauriEL I said that to someone once, who argued with me that needing glasses isn't a disability because it's accommodated.
I pointed out that their guide dog was an accommodation, but they were still blind. And that someone who used a wheelchair was accommodated but still needed it for mobility.
Glasses aren't any different, just (as you said) more accepted. The biggest difference is that no on ever touches someone's glasses, yet folks are constantly petting guide dogs or pushing wheelchairs.
