Well, the thing is, his movements are fairly stationary/calculated when he performs, so he just focuses on his hands and what’s close because he doesn’t want to be distracted by outside elements.
He has a good idea just based on the volume/shape of light, of where things are. He does switch when he needs to.
(yes, he’s wearing a cloak over a long coat, because he gets cold easily)
Happy Belated Holidays :^)
