Ophthalmic Genetics, 2004
The science of color vision testing has evolved since its inception in the late 1700s. Since then, the rudimentary technique of comparing color names has been replaced by more sophisticated methods. Commonly used tests in clinical practice today include isochromatic plates, arrangement tests, anomaloscopes, and lantern tests.

Color is a fundamental aspect of normal visual experience. This chapter provides an overview of the role of color in human behavior, a survey of current knowledge regarding the genetic, retinal, and neural mechanisms that enable color vision, and a review of inherited and acquired defects of color vision including a discussion of diagnostic tests.

Ophthalmology Clinics of North America, 2003
Many visual disorders produce acquired color vision defects. Color vision theory emphasizes several stages of visual processing: prereceptoral filters (lens, macular pigment, pupil), cone photopigments (L-, M-, and S-cones), and postreceptoral processes (red-green, S-cone, and luminance channels).

Color Vision in Color Display Night Vision Goggles
Aerospace Medicine and Human Performance, 2017INTRODUCTION: Aircrew viewing eyepiece-injected symbology on color display night vision goggles (CDNVGs) are performing a visual task involving color under highly unnatural viewing conditions. Their performance in discriminating different colors and responding to color cues is unknown.METHODS: Experimental laboratory measurements of 1) color ...

COLOR VISION AND RECENT DEVELOPMENTS IN COLOR VISION TESTING
Archives of Ophthalmology, 1946THIS report is a brief, greatly simplified expression of the working hypotheses being used by color vision investigators today; a note on the ICI Coordinate System and Standard Observer; a short report on some of the developments resulting from Inter-Society Color Council (ISCC) and other activities; a notation of some typical color vision tests in ...

American Journal of Ophthalmology, 1924
This is a brief presentation of theories of color vision as based on four primary colors, red, yellow, green and blue. The way in which these may be associated to give other color effects is illustrated by diagrams. Read before the Utah Ophthalmological Society, May 19th, 1924.

Cell Biophysics, 1986
Two main topics will thread their way through this paper: The structure of the monkey striate cortex, including its inputs and outputs, and the physiological basis of color vision. When Margaret Livingstone and I began this work four years ago we did not set out to study color, but the structures in the cortex that we have been looking at turn out to ...

Schopenhauer on vision and the colors
Documenta Ophthalmologica, 1997Arthur Schopenhauer (1788-1860) published his book, On Vision and the Colors in 1816. He started from Aristotle's linear color system and Goethe's three pairs of contrast colors. His work preceded Hering's theory of opponent colors but his path to insight was blocked by his anti-Newtonianism and his neo-Hellenistic attitude toward science.
