ABSTRACT:
An apparatus and a method for assisting in the selection of corrective lenses includes a spectacle frame having at least one test mounting lens emplaced in the eyepiece of the frame. The test mounting lens has a horizontally elongated aperture for releasably and slideable receiving a telescope holder therein. The telescope holder releasably retains a telescope within it and rides in the slot for positioning the telescope in a position that allows a person being tested to see through the telescope. The method includes placing a telescope of a selected optical strength in an apparatus having a telescope holder; placing the apparatus on a person to be tested in the way that spectacles are worn; adjusting the position of the telescope so that the person can look through it; replacing the telescope initially placed in the telescope holder with telescopes of a different optical strength and permitting the person to view through them; and repeating this step until the person ascertains the telescope that provides the best vision correction.
