The fact that certain brain cells in the visual cortex are more responsive to particular visual stimuli (such as the hands on a clock showing 8 A.M. versus 10 A.M.) suggests that this is an example of feature detection, in which our brains are able to process specific features of sensory input. This does not involve retinal disparity (a difference in the images the two eyes receive), perceptual adaptation (a change in our perception due to continued exposure to a stimulus), or accommodation (adjustment of the lens of the eye to focus on near or far objects).
