Duochrome test
text:
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. Because of the chromatic aberration of the eye, the shorter wavelengths (green) are focused in front of the longer red wavelengths. It is assumed that best vision is attained when the yellow wavelengths are focused on the retina.
