Hmm...not really compatible with eyeglasses. Some can be worn over the front but rarely underneath (unless they are really small frames). Everyone has different frames too so there's no way to make a generic "eyerglasses" mask. It's wear contacts or go a little fuzzy-sighted while you're wearing the mask. ^_^

A lot of people with glasses just wear the mask higher, over their forehead, sort of like a baseball cap.
