I know The Name of the Rose isn't an actual history of the events of 14th century Benedictine monasteries or anything, but the fact that Brother William's lens are seen as magical got me thinking.
What would've been like for me:
(A) before corrective lens were available, (or) (B) once corrective lens were available, but I still couldn't afford them?
How would poor vision (but not blindness!) affect my life and options, as opposed to life blind back then?
