We should continue to explore together the notions of disability and disutility—and please note, these are very different concepts—while being aware of the many barriers to our understanding. We may parse evidence in a concatenation of reductionist steps that seem logical, even statistically significant. Further, we may debate about methods of all sorts: diagnostic, therapeutic, social, medical system, and so on. Still, amblyopia is a real disease with neuroanatomic and neurophysiologic decrements. We humans know a bad thing when we encounter it and we have a sense of how bad things are in a relative sense; these are statements of utility. And, we know the elimination of preventable vision loss in children is a fundamental good.
