Test Duochrome. Duochrome Test Red Green Test FRIEND Test YouTube Duochrome Test The duochrome (red-green) test can be used as a monocular or binocular test to determine the proper spherical power The longer wavelength (red) is refracted less than the shorter.

Because of the chromatic aberration of the eye, the shorter wavelengths (green) are focused in front of the longer red wavelengths. A duochrome test is a test commonly used to refine the final sphere in refraction (under-correction and over-correction), which makes use of the longitudinal chromatic aberration of the eye

A duochrome test is a test commonly used to refine the final sphere in refraction, which makes use of the longitudinal chromatic aberration of the eye The duochrome test involves the projection of black letters or symbols onto a bipartite green (at approximately 535nm) and red (at approximately 620 nm) background The Duochrome test stands as a valuable tool in the optometrist's arsenal, offering a quick and engaging means of assessing visual acuity and identifying potential refractive errors
