I was just in to my eye doc for this same reason. I hurts so much but ,yes, the eye and mouth are the fastest healing parts of our bodies. Doc told me that within 48hrs tops it would heal over. but if you've been touching it you do need an antibiotic since your eye can get a build up of bacteria that can turn into fungus and mess up your cornea permanently. Do not put a patch over it! This allows for fungus 2 grow more rapidly.
