he may still have some lingering eye issues from the bulb, sometimes take a few days to go away, they do close their eyes, i've had babies sleep basking here before too, if it's constant or he wont open the eye then I'd worry but for now, as long as his belly is getting nice and he seems to be relaxing, I'd say he's getting more comfortable and should be coming around to your handling a bit now, have you noticed at all? I like to handle new animals once a day every 2-3 days when i get a new one.
always here,
Charles
