Hi, you said it's one eye doesn't open I heard a YouTube tortoise breeder uploaded a video of his rescue tortoise with a similar situation where the tortoise's had one eye completely shut, and he discovered the previous owner didn't soak him much or not long enough so he was able to remedy the problem by soaking it at least twice per day for 15 minutes at a time & it wasn't a medical condition. Have you ever fed it with Mazuri tortoise feeds? I think you have sufficient light from direct natural sunlight but must not be filtered through a glass window and only directly.I’ve been trying to figure out what species it is , i think it’s a greek tortoise, we’ve had it for almost half a year I think, it doesn’t seem to be eating much so we’ve been trying different greens , it was eating iceberg lettuce but i heard that wasn’t nutritious, we tried rocca and we give it some sweet potato’s occasionally , I live in Jordan and people here don’t have much knowledge about tortoise care , most people i asked say feed it any kind of greens so i really don’t know what to do . Also for the enclosure, we put in a plastic storage container but we don’t have a light currently, there’s a sunny area in my house so we put it there and make sure there’s also an area that’s in the shade and the only time it doesn’t get light is in the night.
