Starting sometime last night our little bearded dragon (approx 6-7 weeks old) started closing one eye. He will open every now and then and it looks fine, but he will not keep it opened. This morning when we offered him some dubia roaches he didn't seem interested, but he ate ok yesterday. I've read a lot of posts on this site about the UVB light maybe hurting the dragons eyes. I have a reptisun 10.0 on the inside of his encloure. It hangs from the back side wall and it hangs down just enough that he likes to climb up and lay and lay on top of the light fixture. Could this be the issue?
