Abstract: Acuity is a function of the photoreceptors of the retina which combine their pixelized stimulation to create the perception of a contiguous image and use that stimulus to regulate the acuity focal length of the biological lens. That image perception is also modulated by the intensity of the light as a stimulus absorbed by those pixelized photoreceptors and, for most individuals, the color frequency of that light. The regulation of visual acuity is primarily determined by the comparative chromatic response of the cone photoreceptors in creating a response matrix to the relative chromatic intensity of the perceived light and using that response to regulate the focal length of the biological lens.
