Description
It provides a comprehensive and clinically based guide to visual optics. With its suggested routines and numerous examples, this new book
offers a straightforward "how to approach" to the understanding of clinical optics, refraction and contact lens optics. Designed for
easy access, it presents information in a concise format that highlights key, need-to-know points. Part 1 addresses the basic visual
optics of the eye along with emmetropia, ametropia and the correction of ametropia with spectacle lenses. Part 2 turns to the optics
of contact lenses and the use of contact lenses in vision correction.
Audience
Undergraduate optometry students; student dispensing opticians; contact lens students.
