Duochrome Test

Chromatic aberration of the eye results in green light being focused in front of the retina, yellow light at the retinal plane, and red light behind the retina. Therefore, when red is brighter, it indicates that more minus is needed to move the focus of red light further behind the retina? When green is brighter, more plus is needed to move the green light to focus further into the posterior chamber.
