Diplopoa
The perception by the same eye of two images of a single object, due to double pupil, early cataract, irregular astigmatism, or displacement of the lens.
Depth perception is caused by having two eyes at a certain distance apart and a brain adapted to interpreting the two slightly different images as one.
The two factors that interact to create a person's perception of an object are stimulus factors and individual factors.
depth perception
a number of images that are formed if the object is placed between two mirrors at an angle. This is called multiple images.
combining two images into a single whole
We see in three dimensions because of the action of our two eyes. Our brain perceives two images simultaneously from two angles, giving us the perception of depth. This is the reason one loses their depth perception with only one eye.

Two eyes allow for depth perception. Close or block one eye and attempt to guess how far (or near) and object it from you.
