My veiled chameleon is about a year old and has been rubbing his left eye on branches and rolling it around, recently he won't even open it anymore and will rarely open the right one. He isn't moving as much and is letting us handle him and he will stay in our hands when he usually hisses and won't let our hands come near him. We tried to flush it out with saline solution for babies and he rolled it around but his eye is still closed and he acts lethargic. This started on Friday.
