User blog comment:D2r/Unanswered Questions of Redwall/@comment-3518397-20110411191411

I've got a potential question, how do the elderly Redwallers who wear glasses know what kind of prescription they need? I'm certain they don't have instruments you'd find at a regular eye doctor's office that can be used to look at the components of the eye closely and figure out what's wrong? How do they even make the glasses?

This may seem like a stupid question but I just thought of it.
