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.

"With its 'hands on' approach, it offers much to anyone involved in optometry and dispensing optics.For anyone studying dispensing optics, it clearly presents and profusely illustrates (in both pictures and examples) many aspects of their study. The many pictures and clear diagrams, including colour plates supporting the contact lens text, complete a worthy addition to the shelf of anyone studying or practicing in the sphere of professional optics today.?Duncan Counter, Dispensing Optics, November 2007
"The style of simple phraseology and examples in the text means of clearly putting across a subject which many think of as dry and boring. This book tries to dispel this myth and does, on balance, succeed.Each chapter has 'concluding points' which are a good summary of what you have read.It is targeted at both undergraduate and newly qualified optometrists, contact lens opticians and dispensing opticians and I believe it is set at the correct level"
