Document Summary

Each eye sees the world in a different angle. There is a consistent distance between the two eyes. From this, we can get info that helps us compute depth. So there is 0 disparity no difference in the image on the hat on the two retinae. Image of this object falls on the same location on the two retinae. The magnitude of the disparity: how far apart is the location of the two images on the retinae. The larger the disparity, the further away the object is from the object we are xating. The horopter is an imaginary sphere that is drawn from our xating point. Eld is made of photoreceptors on the two retinae. The cell will respond optimally when its preferred stimulus falls on the receptive eld, which is de ned in both eyes. The location might be the same location on both eyes, or it might be in different locations on the two retinae.
