Yup. Although I'm also sure that they'd be able to cure many vision impairments. I bet a lot of folks would rather get glasses though instead of going through surgery. It's old school, but I bet some might feel safer. :P Pretty much how it is today. I doubt that as many pendragons wear glasses as humans do in our world though.
Yeah, there definitely aren't many. There's only two that I remember that have them right off hand. Though I'm sure there's a few more than that. Not many more though, lol.
