Not entirely sure about that. From my understanding, the glasses needed in the Closed World (Going by Persona 4 here) is needed to navigate through the mist because you can't see past it. Dominick has been blind for a while, so navigating by sight isn't something he does much anymore. But I suppose the ability to see again, if only in the Closed World, might be something that could build drama for him. I would prefer if he remained blind throughout the entire play through, however, as there is other drama that would arise from his current medical disability.
