I've been at work all day and haven't had time to flush his eye out yet, but I'm home for lunch now and it's already looking better! I think it must be the light causing the problem. How do I flush his eye out? I don't have an eye dropper or anything. The sand is coming out this afternoon. The bulb is sort of near the back of his tank about eight or nine inches above ground level, maybe a foot and a half from his basking spot where he spends most of his time. He has been under that bulb for over a week, but not much longer than that. Two weeks at the most.I have yet to find a Repti-Sun bulb in town, but I'll do some more searching and hopefully I'll be able to get one within a couple of days.
