Title: METHODS AND APPARATUS FOR VERIFYING OPTICAL MEASUREMENTS
Abstract:
Improved optical measuring devices and methods are disclosed for checking certain measurements taken of a patient's face before these measurements are used to create eyeglass lenses for the patient. Embodiments of the invention include a receptacle or bracket for receiving an eyeglass frame having demonstration lenses mounted therein. The frame is held in place, and one or more mechanical structures are provided below the frame which support one or more movable markers, typically one for each lens. The structures are moved according to the measurements taken of the patient's face. A stamping or marking mechanism is provided on each structure which is used to mark the pupil location on each respective lens after the structures are moved according to the patient measurements. The marked lenses are then taken to the patient for verification and modification of measurements, if necessary. Once the measurements have been verified, final lenses may be created.
