"All I see is a blur," he admitted. "I can do a lot of things blind, though, I had to learn just in case. Plus, when I was in school, before I was old enough for contacts, my glasses broke more times than I could count. And it's not like you can just whip out a wand and repair them in the middle of maths class, you know? I usually don't wear them at home so my eyes can relax, I just wander around blind or wear my glasses."
