my water dragon has one eye blind and he close the blind eye all the time. today i saw his eye is opened but it seems like there is a kind of white liquid thing in his eye and it is disgusting. what is the problem with my dragons' eye?

lojjj - is this the first time that he's had his blind eye open? I think that the only thing wrong with his eye is that he's blind. I think that's pretty common for a blind eye.

Someone please correct me, if I'm out to lunch on this.

I don't know if Water Dragons can have cataracts, but it sounds like that could be what you are seeing.

Cataracts are common causes of blindness or reduced vision levels.
