The third edition of Contact Lens Optics & Lens Design is clearer and more accessible than ever before. Without assuming detailed prior knowledge of optics and ophthalmic lenses, Professor Douthwaite provides a straightforward introduction and, moving from a restatement of basic knowledge, builds solutions to the vast majority of contact lens optics problems likely to be encountered by the student or practitioner.

With a new design including colour, Contact Lens Optics & Lens Design has been thoroughly updated and contains new for this third edition:

. integral coverage of soft lenses
. information on the latest corneal measuring techniques
. expanded coverage of astigmatism and corneal toricity
. a new chapter on presbyopia
. separate treatment of orthokeratology

Also included on the accompanying CD is a completely revised and extended set of invaluable computer programs, which allow the student and busy practitioner to bypass tedious calculations in arriving at best fits.

The new Contact Lens Optics & Lens Design is indispensable reading for all undergraduate optometry students and will also be an invaluable guide for contact lens practitioners in helping them to cope rapidly and efficiently with the problems of everyday contact lens fitting.
