    Book Reviews

    From the reviews of previous editions:

    "The format is an intensely practical, hands-on guide to fitting all lens types, from straightforward sphericals through to sealed sclerals… Each chapter is punctuated with different boxes containing practical advice, general advice, rules of thumb and warnings…Unlike most textbooks, it would be quite possible to pick up this book and read it from cover to cover. In fact, I can recommend it." Optometry Today
