I’ve only used them for the respective puzzles so far. Technically you can blind enemies with them, but if you have the choice between attaching a mirror to a shield or a flame/frost/beam emitter instead, go for the latter. Mirrors don’t deal damage. (Maybe they would deal damage to stals, but since the mirrors don’t have any light to reflect at night …well. Duh.)
