Peripheral vision
Peripheral vision is the ability to see objects and movement outside of the direct line of vision.
Functions
The main functions of peripheral vision are:[1]
- recognition of well-known structures and forms with no need to focus by the foveal line of sight.
- identification of similar forms and movements (Gestalt psychology laws)
- delivery of sensations which form the background of detailed visual perception.
Peripheral Vision Media
The eye as a double system: the foveal system delivers 3 to 4 high quality images per second (via the line of sight). The peripheral system delivers up to 90 blurred images per second
Peripheral vision of the human eye
Field of view of the human eye
Classical image of the shape and size of the visual field
Side-view of the human eye, viewed approximately 90° temporal, illustrating how the iris and pupil appear rotated towards the viewer due to the optical properties of the cornea and the aqueous humor.
