Abstract
A method for automatically measuring and quantitatively evaluating the optical quality of an ophthalmic lens, such as, for example, a contact lens. The method measures an ophthalmic lens with an optical phase measurement instrument to derive measured data. The method creates a set of objective optical quality metrics within a computational software. And, the method applies the measured data to at least one of the objective optical quality metrics to determine lens quality.
