Abstract

In a former paper1 an apparatus and method were described for refracting the eye for the peripheral field of vision, and curves were given showing the refractive situation for eighteen cases. It is our purpose in the present paper to make a more comprehensive analysis than was given in that paper of the type of information about the eye that may be obtained by studying the refractive situation from the center to the periphery of the field. Some of this information, so far as we know, can be obtained in no other way of studying the eye that has as yet been described.

The two most important factors in the ametropia for the peripheral field are (1) the effect of the oblique incidence of the rays of light from objects in the peripheral field on the clearness of the image formed, and (2) the effect of size and shape
