I have noticed over the last week that Manny's eye looks a little odd, here's a picture I just took:

If you look closely, there is a gap between his eye and the scales below. It's not red, swollen, puffing out or anything coming out of it, his other eye is normal:

What could this be? He's been eating and drinking fine, his shed was almost perfect and I can't think of anything else what would effect it.
