Okay, thank you very much for that information. It is very helpful.Jacqui has given you good info. I'd like to add - lots of leaf litter all over the floor of the habitat. Many plants either real or fake. The tortoise has to feel safe, and your enclosure is too wide open. Soak him daily for at least a half hour, and if the eyes open during the soak, you'll know he's been kept too dry. If the light bothers his eyes, they probably won't open during the soak. You can buy either one of these products - you don't need both:

These will soothe the eyes.
Maybe buy a CHE (ceramic heat emitter) to heat up the enclosure, and quit using a light for the time being. He will eventually need the light, but wait until his eyes are open all the time.
I've been soaking him in banana baby food and still nothing. I have also tried to get him to eat bananas and that doesnt work eitherOkay, that is a great sign.
As to the above mention of temps, I have found with my own animals, that once temps get in the 80s, mine start slowing down. Just saying what mine have done.
