This book is unfortunately riddled with errors, inappropriate terminology, incompletely explained or inaccurate concepts, mathematical mistakes, and incorrectly drawn diagrams. For example, the definition of "vergence" as a "direction" on page 5 is inaccurate and unusable. The definition of "object space" on page 8 is incomplete, not taking into account virtual object space to the right of the lens. On pages 10 and 14, objects and images are said to "have" vergence, and objects and images are actually labeled with the capital letters "U" and "V," rather than the customary "0" and "I." This will cause great confusion among ophthalmology residents. On page 21, the definition of "magnification" is not an intuitive one, but rather is presented as a mathematical definition of little lasting use to the ophthalmologist. On page 38, "f-stop" is confused with "aperture." On pages 42 to 44, the term "chief ray" is used where "central ray"
