Foreword
Textbook of Visual Science and Clinical Optometry is a wonderful
knowledge book for the ophthalmic practitioners, optometrists and
students of ophthalmology.
This book explains the anatomy and physiology of the eye in
a very well-formatted concise manner. It enlightens the optical
defects and its correction in a most lucid and methodical way. In
the glamour of ophthalmic innovations, the fundamental optics and
refraction of the eye have become a forgotten territory.
I thank Dr Bikas Bhattacharyya for bringing out this book in
such a “transparent and structured format”. Bikas, 2 years junior
to me in Medical Education in the same University, is always
remembered for his unusual inclination to minute details and
documentation. This book is reflection of his qualities.
I am sure we will learn a lot of skills from this book and use
it for more efficient eye care. This will be the most fitting tribute
to the hard work that he has put into writing this book.

Preface
Textbook of Visual Science and Clinical Optometry is designed to cater
to the needs of eye care team which includes ophthalmologists,
ophthalmology residents, optometry students and ophthalmic
technicians.
The book includes 18 chapters which are divided into 6 sections
and each chapter is supplemented by numerous illustrations. Every
attempt is made to make this book as clinically relevant as possible.
Section 1 to 3 deal with the normal human eye and its optical
principle. Section 4 deals with the different types of refractive errors
and its correction. Section 5 stresses on the various optical lenses,
frames, measurements and contact lenses. Knowledge on these
topics (Section 5) is usually not covered in books on ophthalmology.
The last section is unique in a way as it covers three special
chapters on ophthalmic instrumentation techniques, low visual
aids and paediatric eye examination, which is invaluable to all
those involved in eye care.
I hope that my humble efforts would prove successful in helping
the beginners in ophthalmology. I have tried to make the topics as
comprehensive and simplified as possible. However, certain
inaccuracies may arise for which I apologise sincerely.
Any suggestions and comments on the book would be greatly
appreciated.
