Do you assert that he does not wear eyeliner? Or are you saying that he does but it is ridiculous to ask why?
W.R.T. the former, I think you're just mistaking the contrast of his light colored eyes w/ his darker facial features.
But the latter question is also ridiculous... people who are in the public eye and are always being photographed wear makeup. That just comes with the territory in a modern life.
At this point, I don't even believe I'm entertaining your childish non-sense.... don't expect another reply.
