The standard text on the theory and application of spectacle lenses. Written for students of optometry, dispensing optics and optical technicians, the book covers the mechanical, optical properties and design of ophthalmic lenses. It includes several original graphic solutions to problems which arise in the design, manufacture and dispensing of lenses. The author, recognised as an international authority on the geometrical optics of ophthalmic lenses, obtained patents for the new generation of low-power aspheric lenses in 1980.

Essential reading for the following ABDO College courses:
