I have an acquaintance who lost the vision in his left eye due to a wreck. Fortunately he is right handed and was always right eye dominant. After his recovery, he was having trouble hitting clays at first, but within two months he seems as good as ever, and he was nailing the ducks this past season. Just keep at it and give it a little time is my advice.
I can sympathize. I lost 100% of my hearing in my left ear due to a sneeze of all things. The only thing they can offer that has a high chance of success at recovering some hearing is a cochlear implant. But, a lot of people have most of their hearing come back gradually over time, so right now I am waiting and hoping.
