My chameleon might be hurt, what do i do?

i have two veiled chameleons that are a couple months old, one male, one female. thye have always been in the same cage since we've had them, but recently they get in fights every now and then, is this normal? or do they need to be separated? just now my male attacked my female and her eye got slightly pushed in, the part of the eyelid that is extended got smashed with it, there was no blood or anything though. the problem now is that she cant eat because her vision is off. she cant see straight to actually get the cricket (i kill and hand feed the crickets to them myself, so i know this) what do i do? will it fix its self or does she need medical help? please help!!
