I haven't noticed any serious eye dents in my boy yet but I have been having humidity issues on the warm side of my tank but not the cool side. Cool side ranges are 75-77F with 65-70% humidity at all times but the warm side always manages to drop to around 40-45% (temps 88F) when I leave for the day. I'll mist it a few times a day and have about 75% of the top covered. I also have a humidifier in my room. I seem to be doing everything correctly and the cool side humidity is perfect but the warm side just won't stay up
