ABSTRACT:
There is provided a frame measurement platform for measuring the perpendicular distance between the two temples of an open eyeglass frame, and a method for using such a device. The platform includes a support, two spaced-apart reference members which are moveable with respect to each other, and measuring scale. The reference members define respective temple measuring planes which are substantially perpendicular to a reference measuring plane defined by the support. The measuring scale is used to measure the perpendicular distance between temples of an open eyeglass frame.
