Harry is a seeker, but he is supposed to have very bad eyesight. "Harry, your eyesight really is horrible.'' Hermione Granger, Deathly Hallows. It seems that those of us who wear corrective lenses can see things other people don't. People have commented on the fact that I have a knack for seeing things that other people cannot. I'm rather observant, if I do say so myself. Maybe glasses make you more observant, as you can't see the world with your regular eyes?
