Types of vision

TYPES OF VISION

Monocular or periscopic

  • Laterally placed eyes (frog and reptiles) viewing the object independently due to wide visual angle between optic axis and mid line of the eye.

Binocular vision

  • Anterio laterally placed eyes (primates, carnivores, birds), both the eyes view the same object simultaneously, overlap of field of vision due to parallel optic axis and mid line of the eye.

Stereo vision

  • Anteriorly placed eyes (cats) Dissimilarity in viewing the object by left and right eyes, three dimensional view due to very small angle between optic axis and mid line of the eye, fusion of the image by the visual centre.
