Brandon,
I think your snake may have a retained (un-shed) eye cap (I think its called a speculum). What happens is that sometimes the speculum doesn't come off with the skin. Do you still have the last shed skin? If you do, check to see if the scale that covered that eye is missing from the shed. If it is missing from the shed skin then it is most likely the cause of the symptoms you describe.
This condition usually resolves itself naturally at the next shed. However, it can cause an impacted speculum if it continues to fail to shed. Obviously, this is not a good thing - the eye will sort of die and go blind.
A long time ago I got a red sided garter who had had this happen - it was like there was a black mass in the socket. It didn't seem to bother him much, but it looked gross.
I had a large chain king that occasionally failed to shed a speculum. The first time I took him to the vet. He used a blunt tweezer to remove the speculum. After I had seen it done, it was easy to do it myself. However, before going that route, try soaking or placing the snake in a damp environment, then try rubbing the speculum with a damp towel. Sometimes the snake can get it off with out help if conditions are damp enough.
I agree with the previous posts - a herp vet is a very good idea.
Anyway, That's what I think - Just remember, free advice is worth every cent you payed for it.
Good Luck,
John D
