I don't know much about moonblindness or its causes but I know its one of the most serious eye problems a horse can have, its common enough,and its very painful to the horse.
It also stays coming back and needs agressive treatment. I would get him straight to the vet. Good luck, hope he's okay
I agree with the first thing, but if he has had the cloudy eye and you have already had it checked it may not me. He might have just got something in it. In that case take some saline solution and wash his eye out with it. Then make sure you wash his eye out. It should get better. If it isn't the next day then it could be something else in which that case I would call the vet. Is the nostril on that side running? He could have maybe ruptured a tear duct. But there could aslo be something on it you just can't get off and it will cause cataracts if you don't get it taken care of by a vet.
I don't agree that moon blindness is very painful all the time for every horse. Gizmo has had moon blindness in his one eye now for a long time and I have never had a problem with it. Sometimes when its very windy it will water a little and bother him, but I put one scoop of asprin in his feed and it clears right up. There are plenty of cases where they are just like Gizmo but there are times when it is painful for them and they have to get the eye removed. It really depends on the condition of the eye.
Oh and I forgot, if you have any AniPrin asprin or something like that, you might want to try that as well. It could just be the wind or cold weather bothering it. I think cloudy eyes (or glass eyes) get very dry in this kind of weather.
