ABSTRACT:
An eyeglass frame fitting system is disclosed comprising a fitting frame with horizontal and vertical slides having apertures to measure horizontal pupil distance and vertical pupil position. Pupil location measurements are taken by viewing a distant target through the apertures which are aligned to allow unobstructed viewing of the target. The fitting frame also has temple slides to measure temple length. The fitting system also comprises a nose bar for measuring an individual's nose size and a head width slide for measuring an individual's head width. The fitting system is designed to be inexpensive and usable by any individual without the need for any technical knowledge or experience.
