ABSTRACT:
A device for measuring the dimensions for locating multifocal segments on eyeglass lenses. A chinrest is provided for maintaining the stability of the patient's head while the proper location of the multifocal segment is determined, and an eyepiece is provided through which the dispenser may look at reference points on the face of the patient and the patient's new eyewear to measure the required dimensions. The eyepiece is then moved along the vertical axis of the post to which it is mounted, and the distance traveled by the eyepiece between the reference points is measured by a measuring device found on the apparatus.
