This book is a comprehensive account of the most recent developments in modern ophthalmic optics. It makes use of the powerful matrix formalism to describe curvature and power, providing a unified view of the optical and geometrical properties of lenses. This unified approach is applicable to the design and properties of not only spectacle lenses, but also contact and intraocular lenses (IOL). The newest developments in lens design, manufacturing and testing are discussed, with an emphasis on the description of free-form technology, which has surpassed traditional manufacturing methods and allows digital lenses to be specifically designed with the unique requirements of the user. Other important topics which are covered include modern lens materials, up-to-date lens measuring techniques, contact and intraocular lenses, progressive power lenses, low vision aids, ocular protection and coatings. Providing a broad overview of recent developments in the field, it is ideal for researchers, manufacturers and practitioners involved in ophthalmic optics.

The first book to provide an in-depth introduction to this topic and to offer instruction on how to set up and operate a system of this type. This book is divided in 3 parts, the first of which covers the relevant background information, including an introduction to the human visual system and key issues in visual perception and eye movement. The second part surveys eye tracking devices and gives a detailed introduction to the technical requirements for installing a system and developing an application program. The final part looks at potential application in areas such as human factors, collaborative systems, virtual reality, and marketing/advertising.
