I see in one of your previous replies that you did mention that your uvb bulb has three "prongs".That IS a compact flourescent and those are the very ones KNOWN to cause eye problems.If you want your Cham. to recover you MUST get the other type [ long tube ]uvb bulb,like repti-sun 5.0.If your pet-shop guy is the one that you got the cham.from and your supplies,then he obviously will not have a clue about the problem.Just get your bulb changed,that is almost certainly the problem.
