would you return fire if someone hit you with a paintball?

A paintball fired at a person's unprotected head has a significant likelihood of causing permanent disfiguring and/or blinding injuries. Such injuries would meet the standard of "severe bodily harm" required in many states for use of lethal force in self-defense.
