Abstract

PURPOSE: To prevent the progression of short-sight by letting the upper half and power half of the lens vary by requried diopters.
CONSTITUTION: The progression of short-sight is prevented if the spectacle lens is used dividedly in the case of viewing far and near portions by letting the upper half of said lens have the diopter corresponding to short-sight in order to identify the far-distant objects and letting the lower half be the lens having no piopter or of weak diopters so as to give no undue stress to the eye ball as the lens for close- distant objects.
