According to some google sources, both women have an autoimmune condition called Graves which affects the eyes. At first I thought Lightfoot's eyes looked bizarre. But I realized they're haunting and beautiful, like Bette Davis's.
I'm trying to be fair. I don't like attacking a woman's looks. "Menacing"? Hahaha. Ghoulish and beautiful? They are very striking and I have a difficult time describing them.
