Hey I think I can help, I just had the same prob it was like that for weeks and weeks and I fixed it, do u have light right next to the cage that he goes under of so move it farther back, my Cham was getting to close to the bulb when he basked and it was dryin out the eye, that's why he's trying to clean it alot but there's no water there to clean it, move the light or the basking spot farther back so he can't get that close and within a day it should go back to normal slowly ! Hope
This helps it worked for my Cham
