Yeah, cuz in real life blood never splatters on your face.
That doesn't mean you'd see it.
If you got blood in your eye you would see it.
No, you wouldn't. When you get fluid in your eyes you do not see little dots. Eyes are small, 1 drop is enough to make you squint.
I don't think it's a huge issue but I do hate when games do it. It makes it feel like you're either wearing glasses or watching blood splatter on a camera lens.
