Whether the red-green balance point in subjective refraction is influenced by higher-order aberrations (HOAs), thereby leading to positive or negative outcomes from the residual low-order aberrations (LOAs) and HOAs after refractive correction, remains to be investigated. Under white light conditions, it is also unclear whether the impact of chromatic and monochromatic aberrations on visual functi
