Image Formation
- Accommodation is the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies.
An example of shape constancy.
- The retina is the third and inner coat of the eye which is a light-sensitive layer of tissue.
- The fovea centralis is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina.
- Visual acuity commonly refers to the clarity of vision. It is dependent on optical and neural factors.
The diagram shows the relative acuity of the left human eye (horizontal section) in degrees from the fovea.
