What do i do if i got a little peroxide in my eye?

Flush it out: Peroxide in commercial concentrations will do no harm to your eye if you got a splash or two into your eye. You could flush it out if uncomfortable but do not worry. See an ophthalmologist if you have a change in the vision, have pain or redness - but these are very, very unlikely in this circumstance.

Rinse immediately: Peroxide is very irritating. If you get any in your eye, rinse your eye immediately. Should you still experience any significant pain, see a doctor.
