Abstract
The invention relates to a multi-optical-axis progressive spectacle lens measurement method. Due to the facts that visual axis of each eye can rotate correspondingly and multi-optical-axis change is presented when the human eyes actually observe objects in different directions, multi-optical-axis measurement conforming to the reality is conducted on a progressive spectacle lens. A lighting light path outputs aligned and straight laser beams, and after the laser beams pass through the center of an area to be measured of a progressive spectacle lens to be measured, incidence on a 4F system by the laser beams is conducted, wherein the progressive spectacle lens to be measured is fixed by a locating device. A hartmann-shack sensor receives an output light wave of the 4F system. The progressive spectacle lens is fixed to the locating device of the progressive spectacle lens to be measured and can rotate on the locating device according to needs. The exit pupil of the progressive spectacle lens to be measured and the entrance pupil of the hartmann-shack sensor are connected through the 4F system. The conversion relation between detection values obtained through the hartmann-shack sensor and the actual diopter and the actual aberration of the measured progressive spectacle lens is obtained through derivation, and therefore more reasonable diopter information and more reasonable aberration information are obtained. Therefore, a measurement result is more reasonable and more accurate.
