Physiological characteristics of macula for forming binocular vision

Morphology and physiology of the macula Cones within the area unit are of 3 colors: blue spectrum, green and red. The foveolar consists from solely red and inexperienced cones. navy blue cones area unit found within the rings placed round the foveolar, with an outdoor diameter of roughly four.5 mm. The density of blue cones at intervals this ring has the very best concentration. This ring apparently plays a number one role within the physiological mechanism of aiming the attention for the very best accuracy.
