Abstract
An ophthalmic lens is designed so that its refractive power is constant whe
n the observer looks through the center of the lens, as well as when the ob
servation is made through the edge of the lens. This state of correction of
an ophthalmic lens can be confirmed by direct measurements of the dioptric
refractive power by means of a typical lens meter, if some special precaut
ions are taken. Here we describe a method to perform these measurements. (C
