Tomonori does not wear glasses because his vision is imperfect; very few wizards have injuries, illnesses, or disabilities that cannot be healed, and his parents would have healed them long before he had cause to think about it. He wears glasses because they are enchanted to detect magic. There are not many students currently wearing or wielding artifices, but this one is! His sword, which has been enchanted, is one of the coolest things Tomonori has ever seen. It's hard not to run over to ask him about it- instead, he manages to walk over at merely a brisk pace and ask:
"Can I look at your sword?"
