What should I do if I splash hot soup in my eye?

Cold compresses. Try cold compresses against your eyes. Usually very little hot soup actually passes your eye lid, but if so, your body naturally develops tears and inflammatory effect to rid the foreign objects. Cold compresses will relieve the pain while your body heals itself. If the hot soup causes burns, see your physician for possible cream/ointment to put on your eyelid and skin. L hope this helps!
