We Have Two Eyes, but Why Object Can We See Just One?

The vision angle is the angle formed by the object and the eye. The angle of vision of each person is different, depending on the distance of objects. Angle left and right eye vision is also different. Objects will be seen one, though seen with two eyes, right and left eye, because the brain regulate the two angles of vision of our eyes.

Although we see with two eyes, the object the seen only one. With two eyes, we can see the object as a whole. Our eyes can also see the distance, do far or near. Try closing one eye, plainly down the stairs or attach the two ends of a pencil, ane will soon know the difference when viewing with two or one eye only.
If you see only with one eye, we can not know the actual distance, do near or far
