Full Description
This up-to-date text offers a practical approach to the theory and practice of how spectacle lenses are made and how they work in correcting vision. It also covers the more fundamental aspects of spectacle lens dispensing with relevance to areas such as visual optics and geometric optics.Pitched at the correct level for study - easy to follow for undergraduates
Theory is related to practical reality - so students can take the textbook through to the early years of practice
Extensive examples enable the reader to follow through calculations - great for revision and quick reference!
