My cage isn’t long enough for a linear light like that.
He usually spends his time at the top, so I’m not sure I understand why it needs to penetrate so deeply.
This was a set up we could afford and which fit recommendations from pet store.
He used to eat about 5 lrg crickets a day. He was an active hunter. We also gave him lrg meal worms dusted in vitamin powder pretty frequently.
He used a water stopper system pretty effectively. We watched him drink from it in store before we purchased him.
Now I am running a warm air humidifier for a period of time each day and misting him multiple times.
After his illness, I syringe fed him a carnivore meal supplement powder that I mixed into a paste. I purchased it from his vet.
We purchased him as a little fella in September 2022. He grew quickly and she’d multiple times.
He was handled infrequently before illness. Now, as I said initially, I am needing to handle him for care daily.
I understand that it may be frustrating to get different information here vs the pet store. However 99% of chams purchased in pet stores are sold with the incorrect set ups. And almost all of those are sold with the incorrect UVB lighting. This leads to infections, decline, Metabolic Bone Disease, and eventually death.
Chameleons are one of the most complex animals I have ever kept. They are also one of the most expensive to set up in a proper enclosure with the right stuff to support health and thriving. Unfortunately Pet stores to not typically explain to people the difficulty or the expense that comes with keeping chameleons.
Without the proper lighting your chameleon will continue to decline. The cage I am guessing is a chameleon kit size which is also much too small. So that is why I gave you the link for the 24 inch fixture. An adult chameleon has to have a 2x2x4ft enclosure which the light I gave you the link for will fit.
There are additional aspects like supplements that if you were told to buy the wrong ones can contribute to extreme health issues.
Young Chameleons should be taking down more like 2 dozen crickets a day. This is very typical under 9 months old. Due to their rapid growth rate. One reason your cham was eating so few is due to the UVB lighting. The UVB lighting is what stimulates their appetite as well. It is the equivalent of what the sun does for them in the wild.
This link will help teach you what you need to make the environment right for the chameleon to start to heal.

Without changes the cham will continue to decline. I am not trying to be harsh just very honest. Taking the cham back to the vet at this point is not something I would do. Based on the enclosure the husbandry issues are the cause of why he is not bouncing back and why the eyes are still having major issues. Without the cage changes and lighting changes you will just waste money at the vet.
