Two Eyes Science Experiment

Close one eye and attempt to put the cap on a fountain pen held at arm's length.With one eye still closed, attempt to put a pencil into a hole which it just fits.Try the same things with both eyes open.Hold a book several feet in front of you, with its edge toward you.Look at it first with both eyes open, then alternately with one eye closed and then the other.What are the results?

Evidently each eye forms an image of an object viewed from a slightly different angle.The effect of this is to give us a sense of the thickness of objects, and also of their distance from us.The brain is able to interpret the angle formed by the rays of light coming from the object to the eyes, and consequently we are conscious that one object is farther from us than another.Pictures viewed with an instrument called the stereoscope give an impression of depth and distance such as an ordinary photograph fails to give.The two pictures which are mounted together have been taken with a double camera, the lenses of which are the same distance apart as the human eyes.
