For example, the size of an object, the orientation of the object, and its distance from the observer are conflated in the retinal image.

Blurred retinal images are not of much use, and the eye has a mechanism that'cuts off'the processing of retinal images when it becomes blurred.

24.
These regularities permit the visual system to use fragmentary information present in the retinal image to draw accurate inferences about the physical cause of the image.
25.
The retinal image is the main source driving vision but what we see is a " virtual " 3D representation of the scene in front of us.
26.
For example, when we make inferences from the retinal image, the knowledge that we live in a three-dimensional world is essential to the correct interpretation of the image.
27.
Those visual areas of the brainstem and cortex that perform the first steps of processing the retinal image tend to be organized according to very precise retinotopic maps.
28.
As Gogel ( 1969, 1997 ) has repeatedly emphasized, there is no " sensation " which could be called the " perceived retinal image size ", " R2 ".
29.
In 1989 Antonio Medina Puerta demonstrated with photographs that retinal images with no parallax disparity but with different shadows are fused stereoscopically, imparting depth perception to the imaged scene.

This increases retinal image size, allowing " more precise focusing . " In fact, image magnification in chameleons is higher in a scaled comparison to all other vertebrates eyes.
