fish can not see please help

[nocatch]

hi has anyone seen this I bought some fish but I did not get a chance to really look at them because the person that I bought them from already had them in a bucket so i could not see them good and it was getting late, so when I got home i put some of my water in the bucket for about 30 to 40 minutes then put them in my tank. The next morning I found that all the fish that I bought had Ick and he did not tell me.so I remove them all, two days go by and now my clown fish is having a had time seeing I put food in he can smell it but can not find it,but if I put the food next to his mouth he will take it and two of the new fish also has the problem .Does anyone now anything about this. Ps the eyes are not cloudy at all. Please help I am trying to save these fish. I called the person and told him to go (*****) him.
