Sounds like you ought to get her to a vet. I'm not sure at that age, but perhaps she's got an infection. Is she still with her mother? If she is going to stay outdoors, she really should be seen by a professionsl. To open her eyes, you could use warm, moist compresses. I hope someone with more "kitten" experience replies, as they have needs that are undoubtedly different from adults. And two weeks is very young.
