Binocular Vision and Stereopsis: How Depth Perception Works #3507420 (License: Personal Use)

This diagram illustrates the geometric principles of human binocular vision: two eyes (labeled "Ojo Izquierdo" and "Ojo Derecho") focus on a common "Punto de Fijación", with light rays converging to form slightly different retinal images. The resulting "Disparidad de imágenes" is processed by the visual cortex to perceive depth, while the central "foveas" ensure high-acuity vision at the fixation point. The red and blue lines trace the optical paths from the fixation point to each eye’s fovea.
