Because we have binocular vision, when we view something we see it from slightly different angles. This difference is interpreted by the brain through experience and a three dimensional picture is built up.
We see objects and perceive depth in three dimensions.
Most animals with binocular vision, such as primates, birds, some reptiles, and some mammals, have the ability to perceive depth and see in 3D. This is achieved by the overlapping field of view from both eyes, allowing them to judge distances and perceive depth accurately.
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.
Having both monocular and binocular cues allows us to perceive depth in a variety of situations. Monocular cues, such as relative size and overlapping objects, help us judge depth when looking at objects with one eye. Binocular cues, such as retinal disparity and convergence, provide us with depth perception when using both eyes together. The combination of these cues enhances our ability to accurately perceive depth and distance in our environment.
Monocular depth cues are visual indicators of depth that can be perceived with one eye, such as size, texture gradient, and linear perspective. In contrast, binocular depth cues require both eyes to perceive depth, primarily through binocular disparity, which is the slight difference in images received by each eye due to their horizontal separation. While monocular cues can provide depth information from a single viewpoint, binocular cues enhance depth perception by combining the views from both eyes.
The two binocular depth cues are retinal(binocular) disparity and convergence. They help us judge reality by giving us a perception of how far away an object is.
I am a computer program designed to process and analyze information based on data inputs. I do not have the ability to perceive depth or distinguish colors like humans do.
A stereocamera works by using two separate lenses to capture two slightly different images of the same scene. The brain then combines these two images to create a sense of depth perception, similar to how our eyes work together to perceive depth in the real world.

Yes, your depth perception can be affected if you close one eye because depth perception relies on the brain processing visual information from both eyes. Closing one eye limits the brain's ability to combine the visual data received from each eye to accurately perceive depth.
Binocularity evolved because it gave early predators the ability to better determine direction and distance of prey. In more advanced organisms, binocularity permits the organism to perceive depth.
