The purpose of this thesis is to provide an easier means for Contact Lens I students to conceptualize corneal-lacrimal lens-contact lens relationships. Included are such principles as apical touch, apical clearance, effects of astigmatism, eccentricity, diameter of the contact lens, lens lag, and the effects of peripheral and intermediate curves. These principles are illustrated by means of transparencies for the overhead projector along with slides and handouts. An extensive literature search was also conducted to provide information on the best methods of visual aid production and utilization.
