Evolution doesn't effectively filter out characteristics that manifest after breeding age. In fact, there tend to be evolutionary advantages to shorter life expectancy after reproduction. Those of us with the sense to use sufficient lighting are consuming resources that could be used for population growth and causing a bottleneck in the genetic churn.
