In the last few years there have been many papers in vision science journals about visual factors in dyslexia, but these findings have not been widely disseminated to the professionals who care for people with dyslexia. Dyslexia and Vision aims to provide a straightforward summary of work in this field for teachers, educational psychologists, child psychologists, and paediatricians. The primary purpose of the book is to provide these professionals with the information they need in order to offer balanced, insightful advice for people in their care. Eyecare professionals themselves are often bewildered by the plethora of claims and anecdotes in this field. A secondary purpose of the book is to provide, in appendices, a balanced "evidence-based" review of the literature for eyecare professionals.

Developing healthy visual-motor abilities is more difficult in the complex stimulus of today's world than ever before. Our visual experiences can be overwhelmed by the vast complexity of artificial colors and sounds which did not exist in our ancestors' lives. Much more time is spent indoors, exposed to a myriad of unnatural colors, movement and imagery. We hibernate inside, interacting with machines instead of being out in the sunlight, looking at the far horizons, exploring natural environments. More and more time is spent sitting rather than moving, watching rather than doing. Here is a book that has: An overview of the development of vision, with a checklist of warning signs of vision problems-based on the studies of behavioral optometry; A discussion of the importance of integrating all the senses equally in the development of optimal visual skills, rooted in the field of occupational therapy; Practical, playful activities designed to improve visual skills in both adults and children. Excellent for use at home, in the clinic, at school, or amid outdoor settings
