now lets look at the main reasons chameleons get eye infections;
from mites, dirt or calcium in the eye, from eye scratches, or from bacterial or fungal infections related to the above. generally speaking imo, healthy thriving chams are much more resistant to bacterial and fungal infections than unhealthy chams. what this means is that if you are relatively sure of your husbandry, to the point where you are confident that its eye issues werent caused by scratches or mites, dirt or calcium getting in the eye. then your eye issues are more than likely metabolic, meaning a significant imbalance in overall whole body chemistry.
metabolic eye issues, are often thought to be related to vitamin A issues, but vitamin A issues arent so straight forward either. imo, its rarely just an issue of too little or too much vitamin A.
vitamin A is often blamed for eye issues, but a vitamin A deficiency is not necessarily an issue of not giving enough vitamin A. imo, vitamin A deficiencies often appear in animals where the info given indicates that the animal is receiving more than enough vitaminA.
now you ask how is this possible? because other things can create scenarios where it is difficult or impossible for the animal to absorb/utilize vitamin A, or other nutrients, even though its being given theoretically more than enough.
imo, the most common and obvious example of this, would be an ongoing over-supplementation of calcium/d3, which is strongly implicated in issues of interior calcification. if an animals organs begin to calcify (for what ever reason), they begin to shut down and cease to function properly. in a situation like that, deficiencies may begin to surface, even though they were initially brought on by over supplementation.
if an animal is displaying what appears as a vitaminA deficiency, because the organs are shuting down and no longer functioning, then it wont matter how much vitamin a you give it, until you correct the issue that is causing the metabolic imbalance in the first place.
imo, what needs to happen in many of these cases,(not necessarily yours) is that they need to get less supps (even though they may be displaying as a deficiency) so that the metabolism can regain some balance and allow things like vitaminA to be absorbed/utilized again.
scenarios like this, are what make the entire supplementation dynamic so hard to pin point, because a simple d3 oversupp is rarely just a simple case of too much d3, it often relates to the calcium and water intake, calcitonin, pth, hydroxy;dihydroxycholecalciferol conversion and just about everything else having to do with whole body chemistry. and what often appears to be a simple vitaminA deficiency, is often related to d3/calcium issues, and all of the nutrition/supplementation and organs that are involved. (ie more whole body chemistry) (not implying that your animal is calcified or that advanced calcification is reversible), just merely pointing out the complexities of cham supplementation/nutrition.
so the moral of the story is, that everything is inseparably tied together. imo, the problems most often indicated are rarely just a case of
too much d3, too little vitaminA, a simple hunger strike, a simple eye or tongue problem, imo its almost always related to a much bigger issue having to do with whole body chemistry. this is why varied diet, gutloading, lighting/temp scheme and overall husbandry are so important, because you cant separate one from the others. they are all inseparably tied together.
