Yes, I agree I like liquid calcium and dusting that should keep your chams healthy for many years. However, I have heard of people using the eye wash in severe circumstances of eye irritations. For example, my vet recommended using that on one panther chameleon that rubbed his eye on plants and vines in his cage. He rubbed the rotor on one eye and it would not open. My vet just said to use vit. A w/ retinol palmitate and if it got worse then use the eye wash. Luckily in a couple days my panther cham. snapped right back to normal w/ just the vit. A smeared on his feeders for 3 days. and no eye wash was needed. He is big and healthy now and is 3 yrs. old. I have never had a problem since, but my vet said sometimes eye washes are needed. Good luck.
