His eyes are very bright. Usually human eyes don't reflect lights, except for "red dots". His look almost reflective. I know tapeta lucidum (the anatomic membrane that directs the light inside the eye, the reason why cat's eyes fluoresce at night) is the structure humans don't possess, but intense googling brought me to some people having rod-rich retina and seeing very well at night. Would be interesting to find out.
