do you think wizards with astigmatism but without glasses see wisps with those streaks you see late at night from light sources? Do they see someone cast a storm/fire spell squinting like "wow this is weird"? Hopefully you know what im saying bc i dont know the correct term but reading your tag on the post with the diviner and near sightedness I've wondered.. (from an anon with both near sightedness and astigmatism)

AHH i love this question as i am also a person with near sightedness and astigmatism i love the idea of wizards with astigmatism seeing those light streaks (which might be called a refractive error?) coming from the wisps and spells and i think this absolutely would happen to them. in my head, i think wizards with astigmatism would have to get special lenses to correct the fuzzy or streakiness from their spells which might cause them to unfocus - and therefore - fizzle. (thats just what i think though, i dont know if there is an actual in universe explantion for what causes fizzling. i assume that fizzling has to do, at least in part, with vision because the spell smokescreen kind of implies that with the name and the sun school accuracy enchantments have names like "keen eyes" ?????) not to mention things like depth perception when casting spells, i would fuck that up even with my glasses on i like to imagine a young wizard seeing a diviner or pyromancer cast one of their spells, mentioning something about the streaks/fuzziness around their spell, and then having the diviner or pyromancer look at them like they're crazy. or alternatively, the other wizard has an "I KNOW RIGHT??" moment (they both need to get their eyes checked)
