[Reptscue]

First off....welcome to the site.
But you need to get to a qualified reptile Veterinarian. You may have a serious eye infection on your hands and/or retain eye caps. Eye infections can be quite serious if left untreated.
Does it look like it is within the eye or like she is going into shed?
Can you get a picture of it?
Oh and snakes do not have good eyes, they go mostly by scent and vibration.

Good luck with her! Let us know what happens.
