The most likely possiblity is posterior capsule opacification which can be fixed with a painless, in-office yag laser procedure that takes just a few minutes. Other possible causes that come to mind include corneal edema or macular degeneration. Have him see an EyeMD Ophthalmologist - this should be an easy problem to work on.
