So I just did a quick search about vetropolycin and it is for use on cats and dogs. Not only are their eyes much bigger than chameleon's eyes so it probably doesn't matter if it is as viscous because they can move it around in their eyes more. I'm going to bring this up with an exotic vet I know to learn more about it (I would like to be an exotic vet-specializing in reptiles hopefully) and I will let you guys know.
