Abstract: PURPOSE: To provide a simultaneous visual field ophthalmologic lens for presbyopia correction and a pair of the ophthalmologic lenses of this kind for a person wearing the same. CONSTITUTION: At the time of specifying a far visual field area and a near visual field area in this simultaneous visual field ophthalmologic lens for correcting presbyopia, a curve for indicating a proximity degree as the function of a distance from an axis is present in an area between a lower side envelope curve and an upper side envelope curve by a relating specified polynomial for which a coefficient depends on proximity degree weighting corresponding to the degree of the presbyopia of the wearing person. The far visual field area or the near visual field area is reinforced to the other and corresponding surface areas SVL and SVP are related as following. For a reinforced near visual field, 1.8

Abstract: PURPOSE: To provide a method capable of manufacturing an artifical optical lens having a specific magnification contour by starting its process from an artifical optical lens having a different magnification contour. CONSTITUTION: The manufacturing method for an artificial optical lens having a specific magnification contour starts its process from an artifical optical lens having a different magnification contour and corrects the initial magnification contour by a physical-chemical treating method to obtain the required magnification contour and a rotary mask is used for spatially adjusting energy flux.
