There was an older horse I used to ride that had that same thing. He was kept in a stall all the time with his previous owners. He seemed to have "droopy" eyes. They were puffy on the outside but his eyeball looked sort of pulled back. It was from many years without a decent fly mask. We got antibiotics but the damage was permanent...lessening his sight and all.
So in that case, it could be the flies spredding something and I would suggest a vet visit. JMO hope this helps
Also, he could have bumped his eye. It might just be swollen. I'm not sure if you should touch it or not. I wonder if horses can get Sty Eyes......
