The chances of it happening are quite slim but what if you get a nasty paper cut on your eyeball?
In addition, do you sometimes feel that a strand of your hair (if you only have long hair) can also be as dangerous, like, you would flip your hair the wrong way and one strand would slip under your eyelid and your eyeball would be gashed like if a thin paper edge hastily swiped on it?
That must hurt a whole lot. Your eye will bleed. And you could turn blind. Wow.
