Why are your eyes covered

Hogwarts AU

We bring in more and more of our characters to this AU and after I whined about how much I like Sarka SlingBlade87 found him a role too. He's another rich pure blood family's kid (like Aira-ty) and he's some years above Kahan and Aira-ty. He's also in Ravenclaw like Kahan and I can see baby Kahan asking an innocent question while accidentally meeting Sarka at the door of the Ravenclaw common room. Sarka is an albino and as a kid had serious problems with his eyes and he became blind so his rich family got really rare items for him, two of those magical eyes what Mad-Eye Moody had. But because it is a disturbing sight he wears that blindfold all the time to cover them (because of the magic of the eyes he sees through the fabric excellently). But people normally don't ask things like this (why are his eyes covered) from courtesy or fear but a child is too innocent yet and asks it from curiosity. And I'm honestly curious what Sarka answers after the surprise.
