Emmert's Law
A monocular after-image is located on any surface to which a subject fixates while the after -image is present.x The perceived size of the after-image increases as the perceived distance of the surface increase. Shows that monocular cues may be insufficient to estimate an object's length.
Emmetropia
An eye whose image is focused on the retina, rather than in front of behind it. (As opposed to Hyperopia and Myopia).
End-Inhibition
A property of some cells in the visual cortex which respond strongly to either an edge, a bar or a slit which ends within the receptive field.
