The duochrome or bichromatic test is commonly used as a check on the best vision sphere during monocular refraction If the letters on the red side of the chart appear blacker, add -0.25D.

Duochrome Test The duochrome (red-green) test can be used as a monocular or binocular test to determine the proper spherical power In such cases, the eyes might be accommodating, suggesting that a cycloplegic refraction should be performed to obtain accurate results 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
