On a possible explanation as to why most people have small refractive errors.
The case is made that there must be a feedback mechanism operating during the development of the human eye which means that over a population most people have relatively small refractive errors. The possible feedback mechanisms are examined and the conclusion is drawn that chromatic aberration of the human eye may produce visual cues which could be utilized in such a feedback system.
