Cloudy eyes is a condition known as "Cloudy Eye"
I'm not trying to be smart, that's actually what it's known as.
There are different causes, including bacteria, irritation, old age, cataracts, etc. so it can be quite hard to pinpoint a specific cause. How old is the fish? I have a halfbeak that has had cloudy eye for a long time now.....it seemed to improve a bit, but the eyes never became totally clear again. It doesn't seem to affect the fish in any way, so I've never tried medication.
In your case, I'd be worried about him not eating and would probably try some medication.
*Edit* - just noticed the part about the "bad" water......sounds like that may have been what caused it. Lots of particulates could cause irritation, and poor water quality could invite bacterial infection. I'd see if his condition improves with the better water before trying medication.
