She could have something in it mist her real good, and see if she can clean it out you might even try a shower by reflecting the water off the wall and on to her while she sets on a plant or something. If this don't clear things up, and things don't change in the next day or so I would suggest taking her to a good reptile vet to see what is up. A pic of her might give us a better understanding of what is going on as well. Good luck.
HI Karen, Mine has also got the same problem it happened as she was shedding I dont think mine has shed properly or some has got stuck in her eye, she can open it but doesnt keep it open. Has she shed? Just a thought
No she's not shed. Is just happened only just noticed it. She's my boyfriends chameleon.. he hadn't noticed I only seen it last night. Thank you anyway
