Terramycin is an eye treatment product. The product in question is a “wound and infection” product, reading a few minutes doesn’t turn up any information on eye application.
So in short, I would say no… Don’t put that stuff in your chameleon's eye however a call to a vet would be the best bet.
Always doubt about the website of any pharmaceutic company. It is in their best interest (ie money) to say that their products can be used for a large variety of pathology, even if it's not always true.
The key is to base your opinion on studies that are independant.
With that being said, i have no idea what it is nor if it's really good or not. Contacting a vet is definately your best bet!
