Your Cham may be dehydrated, a female I received had the same issue initially both eyes were closed and she was cold from the extended trip. Put her in a warm shower to mister her, got some pedialyte from from the drugstore with a dropper (ask the pharmacist for one). and let her drink a bit of that as well as water. I also rinsed her left eye which seem to have something in it. I flushed it out and put Terramycin which is an ophthalmic antibiotic ointment to help fight eye infections. (as a pre-caution) and no she is fine. I did a search on eye problems in the forums and found a lot of information that was able to help out.
Cheers,
Mark
