Human vision is called binocular vision. Because we can see the object seen in the corner at the same time with the help of two eyes . When a ray of light reflected from an object falls on the retina, the nerve stimulus that it produces spontaneously converges into a single reflection in the brain's focal point , so that we see an object with one eye. The human eye is located at a distance of 8.3 cm from the front of the head. As a result, when looking at an object in a corner, each eye creates a reflection of the object. The reflection is slightly different from one of the two. Both stimuli are transmitted to the brain. The brain combines the two stimuli. The result is a three-dimensional image of the garment.
