The other day one of my basking bulbs blew out so I replaced it with a red heat bulb for a couple days. The same day I switched it he started closing his eye and moving it around while it's closed. I changed the bulb back to a regular daylight bulb like before. It's been a few days now and he's still closing it, sometimes he looks asleep. Any thoughts on the issue? I can't tell if it's both eyes, usually where he hangs out he's only got one eye facing me.
