Diagnosis of Defective Colour Vision by Jennifer Birch
Defective colour vision, or "colour blindness" is a common affliction, particularly in males, where it affects eight percent of the population. There are different types of colour deficiency, each with degrees of severity, and some people have more practical colour recognition than others. This book is a comprehensive treatment of colour blindness. It looks at the causes of congenital colour deficiency, and acquired colour vision defects arising from ocular and general pathology or excessive use of therapeutic drugs. The design of clinical colour vision tests is fully explained and all the available tests documented. Detailed informatin is given on the optimum use of screening, classification, and occupational tests. Examples of typical results in different types of deficiency are included, together with advice on the examination of children and disadvantaged groups. A checklist is provided of occupations requiring normal colour vision or in which colour deficiency is a handicap. This is a practical book, designed for students and all professionals engaged in colour vision screening, but pitched at a level that should appeal to the non-specialist reader.| SKU | GOR005832386 |

"I was paying $11.99/month for Kindle Unlimited but realized I was renting books, not owning them. Bought this PDF and it's mine forever. Never going back to Kindle."
"Switched from Kindle to these PDFs. Same book, but I actually OWN it now. No monthly fees, no app required. Worth every penny."
"Kindle Unlimited kept raising prices. This is a one-time purchase and the file is permanently on my iPad. Best decision I've made for my reading habit."
"I compared Kindle vs this store. Kindle is cheaper monthly but you don't own anything. Here I paid once and the PDF is mine for life. Highly recommend."
"Left Kindle behind after they removed a book I was reading mid-series. With this PDF, nobody can take it away from me. True ownership feels good."
"Was skeptical about paying $18.95 when Kindle shows $3.99, but then I did the math — Kindle Unlimited is $143/year! This is way better value long term."
"Love that I can read this on any device without installing the Kindle app. The PDF works on my laptop, phone, and tablet seamlessly. So much freedom."
"My Kindle subscription was getting expensive. Switched to buying PDFs here and I'm saving money while actually building a permanent digital library I control."
