My turtles bask with their eyes closed sometimes, and I don't use compact flourescent UVB lights.
Do you remember if they shut their eyes basking before installed the Exo-terras?
Do their eyes look normal or do they appear swollen and runny-looking? If their eyes seem normal and they only sometimes close them while basking, there shouldn't be a problem. Since you say you just got the lights, though, keep an eye out for swelling, rubbing, etc. If you don't notice anything out of ordinary, then I wouldn't worry about their eyes sometimes being closed.
