COMPARISON OF A NEW SENSITOMETRIC METHOD WITH USUAL TECHNICS OF REFRACTION

Arch Ophthalmol. 1943;30(4):489-493. doi:10.1001/archopht.1943.00880220081007
Abstract

During the evolution of a new technic of subjective refraction various aspects and results have been presented.1 In the present paper comparisons are made of this sensitometric method with the usual technics of refraction from various static and dynamic viewpoints. The apparatus in its present form is illustrated in figure 1. The knurled knob at the right operates the circular gradients of a specially adapted Luckiesh-Moss visibility meter, and the operator conveniently reads the settings, made by the subject, on the enclosed cylindric scale at the left. The position of the convergence target is shown for a test of near vision. Various details of the apparatus and technic are omitted here, as they have been presented heretofore.1a

SYNOPSIS OF METHOD  The sensitometric is a subjective method of refraction in which the dioptric power producing maximal visibility is determined with the Luckiesh-Moss sensitometer.1a The measurements of visibility are
