Abstract
Theory: Morpho-physiological characteristics of macula for forming shaped binocular vision
1. Morphology and physiology of the macula.
Cones in the Fovea are susceptible to three colors: blue spectrum (440-480 nm), green (510-550 nm) and red (620-770 nm). The foveola (2.2 mm diameter) consists from only red and green cones. Dark blue cones are found inside the rings located around the foveola, with an outside diameter of approximately 4.5 mm (stereo-angle of 180o). The density of blue cones within this ring has the highest concentration [1]. This ring apparently plays a leading role in the physiological mechanism of aiming the eye for the highest accuracy of the image (fig. 1).
This morphofunctional structure of the macula allows you to reliably "aim" for the area of space even in low-light conditions when the coming light mostly consists from the most powerful violet-blue part of the spectrum. Chart of optical center organization in retina presented in Fig. 2 will help you to better understand the Organization of the incoming optical signal with the functioning of the accommodation system.
