My veiled chams right eye seems to be "stuck" looking forward. he only moves it up and down, and he does not move it around nearly as much as his left eye.

I was told to adjust his set up so that he can get more UV lighting and that this would help him out.

Does anyone have any other suggestions or objections to whats happening?

Should I upgrade from a repti-glo 5.0 uv lamp???
