"THINGS AS THEY SEEM"
Well, They Look Different, Using One Eye at a Time. Because We have two eyes the things we see seem solid and not flat, with the result that we can judge their distance from us with fair correctness, says Popular Science Monthly. Look through a window at a house across the street with one eye closed, and then with the other eye closed. The bars of the window frame will cat across the opposite house in different places. The two fields seen with the eyes separately, although in the main alike, differ. When you look at the house with both eyes open the two fields seen by the two eyes combined and the house across: the street assumes depth and relief. Although we see a house with each eye we see only One house with both eyes This makes the stereoscope possible —an instrument so designed that the two eyes are made to converge on a single point and yet to see two different pictures. If these pictures represent a chair as it would, appeal to the right and left eyes, respectively, they are perceived as one solid object.
