The Hunterian lectures on colour-vision and colour-blindness

"The Hunterian lectures on colour-vision and colour-blindness" by F. W. Edridge-Green is a scientific publication written in the early 20th century. Delivered before the Royal College of Surgeons of England in February 1911, the book explores the intricate mechanisms of colour vision and the various types of colour blindness, offering insights into both the physiological underpinnings and the practical detection of these visual conditions. In this work, Professor Edridge-Green outlines his theories on how visual stimuli are processed by the eye and interpreted as colour by the brain. He discusses the structure and function of the retina, particularly focusing on the roles of rods and cones in vision. The book also categorizes different types of colour blindness, explaining how individuals perceive colour differently based on their unique visual systems. Edridge-Green emphasizes the necessity for accurate testing methods to identify colour blindness, proposing various examination techniques, including a lantern test he developed, which becomes a key tool in identifying and understanding this condition. Overall, the lectures serve as a comprehensive resource for understanding the science behind colour perception and the implications of its deficiencies.
