Normally eye infections will cause an eye to have a mucousy discharge and their eyes don't open fully. If this is the case, then they will need to see a vet for antibiotics.
It is safe to use Polysporin Ear and Eye drops a couple times per day (you can get at the pharmacy counter) in kitten's eyes, it will keep the eyes clean. The antibiotics in this is not strong enough to clear up an infection, though. Kittens play so rough with each other, that it is normal to get some eye irritations.
