Eyepoke

[Adam]

If I see the swipe and the reaction, I've seen the foul. If I'm straight-lined on a player running into another one, all I'm likely to see is the intial direction and the reaction. I may not actually see the contact that caused the fall.

No one is saying to call the foul if you don't see the swipe, only that if you don't literally see the finger hit the eye you can still call the foul.
