title: Unresolved issues in the prediction of subjective refraction from wavefront aberration maps.
abstract: Sources of uncertainty in the conversion of wavefront aberration maps to refractive prescriptions are described. These uncertainties highlight the nature of optimum corrections, the imprecise far point in human eyes, multiple strategies for locating an approximate far point, and unresolved aspects of the gold standard for judging success. The conclusion points to future experiments needed to resolve these uncertainties to achieve more accurate and precise methods of objective wavefront refraction.
