Thanks so much for the detailed information; this is very helpful.
There are several possible explanations as to what might be causing this problem with Terrance's eyes which include diet and husbandry issues.
1. Coil UVB bulbs can injure the eyes and cause a problem called Photo Kerato Conjunctivititis. This LINK discusses this problem in detail. I would strongly recommend a tube type UVB bulb.
2. Terrance’s diet needs a little improvement as well. Kale can bind calcium and carrots can cause eye issues if fed on a regular basis. My diet suggestions would be Collard greens, mustard greens, dandelion greens, escarole and curly endives. Butternut squash and various berries are great for a treat. The Veggies should be offered fresh daily about an hour after lights are on. Bearded dragons need 80% veggies daily and 20% live prey.
3. The food should be dusted with plain calcium 5 days a week and the Vitamin 2 days a week.
4. Vitamin A deficiency can also cause eye problems.
Additional suggestions include the following:
1. Use warm compresses on the eyes,
2. Add a Reptile Vitamin with Vitamin A included (not Beta Carotene) since there is a difference in absorption
3. Boil liver and try and feed this to Terrance
4. The live prey should include crickets, silk worms, roaches, goliath worms and phoenix worms. This nutrition chart may also be helpful (LINK).
5. Discontinue the turtle eye drops and use Terramycin instead. This LINK is where you can order it.
It's possible that Terrance may need to see a vet for this problem if you don't see improvement soon.
I hope this helps; again, my apologies for the delay. Deb
