Subject Title
Anatomy & Physiology of the Eye

Subject Description

This subject explores the functional aspects of ocular structures through examination of the gross anatomy of the eye and its accessory organs. The basic principles of structure, function and organization of the visual system and refractive media are included. Students develop understanding of ocular disorders and diseases and the effects of ocular trauma.

Credit Status
One credit toward the Opticianry Diploma Program
