Hahaha, canonically she CAN see, but with the way her eyes are drawn, how her default gaze is basically a blank stare, and the entire motif of candlelight, I actually like the idea of her being blind. My friend thought she was, because a blind poet-knight who loves the written word is very romantic, but alas, sadly she is not. It won't stop me from headcanoning her with extremely poor eyesight, though. It only makes sense if she did do everything by candlelight.
