Dr Brian Boxer Walcher has pioneered treatments in vision correction, has published more than 100 scientific, peer-reviewed journal papers and book chapters, and is the first choice of many doctors for their own eye treatment. In his new book - Perceptual Intelligence, he offers a fascinating, accessible description of how we see what we see and why this affects every aspect of our lives. This forms the basis of our discussion in this interview.

Dr Brian is fascinated by the connections among our five senses — sight, hearing, smell, taste, and touch — and how our brains register and interpret them to distinguish reality from illusion. Defining Perceptual Intelligence (PI) as to how we interpret and occasionally manipulate our experiences to distinguish fantasy from reality. PI relies heavily on our senses and instincts, but it is frequently influenced and distorted by our emotions and memories. I hope you enjoy this interview.
