This book is a lucid and well-written text. It provides an update explanation on optical instruments, materials and techniques being used in the field of eye care. The book is perhaps first of its kind. Thus, it will meet a long-standing demand for a treatise on this subject. The contents of the book ensure a good coverage and their treatment made by Prof Mukherjee is commanding. In view of the present development of several optical techniques used in medical care of eyes, the students of optometry must have reasonably good knowledge in different phenomena relating to optics. The book consists of thirty-two chapters. The first ten chapters of the book deals with different aspects of geometrical optics starting right from Fermat’s principle and its applications for derivation of several useful results in geometrical optics. Chapters from eleven to twenty deal with different phenomena relating to physical optics. The Chapter 21 deals with Einstein’s A, B coefficients in connection with spontaneous and stimulated radiation. Chapter 23 of the book deals with the principle and construction of laser. The next chapter deals with different photometric quantities and photometric instruments used for measuring these quantities. The topics relating to eye-and-vision and the materials used for making spectacles and contact lenses have been dealt with at the end of the book. Useful for the students and teachers of optometry as well as all the professionals involved in the medical care of eye.
