Abstract— Colour vision is a fundamental component of human visual perception, enabling the discrimination, identification, and interpretation of objects in everyday life. Colour vision deficiencies (CVDs), whether congenital or acquired, can significantly affect functional vision, occupational performance, educational outcomes, and quality of life. Advances in colour vision theories—particularly trichromatic theory, opponent-process theory, and modern neurophysiological models—have enhanced the understanding of the mechanisms underlying colour perception and its disorders. This paper critically examines the clinical application of colour vision theories in optometry practice, emphasizing their role in the diagnosis, classification, and management of colour vision deficiencies. Drawing on contemporary research and clinical protocols, the paper explores diagnostic tools, interpretation of test results through theoretical frameworks, and emerging management strategies, including optical aids, digital technologies, and patient counseling. The study highlights the importance of integrating theoretical knowledge with clinical practice to improve diagnostic accuracy and patient-centered management of CVDs.
Keywords— Colour vision, colour vision deficiency, trichromatic theory, opponent-process theory, optometry practice, colour vision testing
