This course includes the practical experiments in visual optics that should be introduced to optometry students to give them a background in optics concerning the eye and ocular examination. The subject matter of this course comprises the application of geometric optics to the specific case of ophthalmic lenses, prisms, and the eye. While the basic fact of clinical practice requires the diagnosis and treatment of different ocular pathology, the vast majority of patients you might see have no pathology indeed and are seeking vision care for refractive or binocular problems. Managing these two important practices (refraction and binocular vision) requires the understanding and application of ophthalmic optics based on geometrical optics. The goal of this course is to teach the important properties of lenses and prisms as they affect the performance of the eye and eyeglass prescription.
