I don't know about bug bites, but I managed to papercut my eyeball when I was young and careless

An optometry student I know says they're unaware of this occurring, as the eyelid will generally catch the bite. If you did get a bug bite on your eyeball, first thing might be cold compress and antihistamines for the swelling and irritation.

When I was in middle school, a girl did in fact get a bug bite on her eyeball. It was blood red for a week and she couldn't see well, but long term she was fine.

No, I can't bite my own eyeball. Neither big nor small.

Ouch

You forgotten how that old joke goes? ;-)

Nah, only small bites. I'll ask next time I see it.

Most likely the eye wouldn't work anymore, or work too well as all the light gets in. What I do know is that impact and even injury to the eye can have drastic effects on both the way the eye works and how your body responds. My dad got hit with a screw in the eye and he still has it, but got bleeding behind the eye and nearly lost it.
