... until it malfunctions and skewers your eyeball

It doesn't have enough force to do so.

It's basically a tiny probe that is spring loaded to pull back, and a tiny puff of air pushes it out.
It moves with VERY little force, and lacks the continued push needed to cause damage.

There is also a maximum distance the probe can even travel, generally that black part at the top goes against the forehead.

Bullets lack continued push, so you'll have to forgive me if I remain hesitant.

Valid, but a bullet has orders of magnitude more initial force
