You need to see if the snake has an eye cap that did not shed. If you can't spot this on your own you may want to take the animals to a vet. I would ask that you post quality pictures here so that people can weigh in with their opinions.

In the mean time, I would put some warm water in a big cooler and lock her in there for a while. I use a cooler because it keeps the water warm and you can slide a piece of 2x2 through the handles to keep the lid in place.

Open it in about half an hour to let some fresh air in there. Your snake will probably hate you for a little while, but if it is an eyecap that didn't come off during shedding it will often be easy to remove after a few hours of soaking.

If you can't get pictures up here and you are inexperienced you should see if a more knowledgeable friend can come and look at the animal. If that is not a possibility I would take the snake to a vet.

Good luck with your snake. I hope that this is the problem.
