Definitely some crusties there so I'd wager that there is some sort of inflammation in the eye.
I'd rinse with some normal saline or warm water compress and treat with bacitracin antibiotic ointment. Just put a dab on your finger and rub it over her eye. She will close her eye, just smear it on her closed eye where the eyelids meet. Some will get into her eye.
Strange looking iris. Any chance she got pecked by another chick?
I have several birds with ocular Mareks and are blind in one eye due to the herpes infection. They get along well, see well out of one eye. They will run into things on their blind side and are more 'skittish' than their normal visioned flock mates but otherwise act normal and hang around with the rest of the flock. One rooster is quite the lady's man and the hens love him.
If she isn't scratching at the other eye or keeping it closed in bright light I'd venture that she isn't too uncomfortable with it. There are several different eye ointments available at TS or Orscheln's for 'animal' eye infections. If you have Bacitracin or even triple antibiotic first aide ointment on hand, it will do for the time being until you can get something else on board.
