Final answer:
The ability to see one image using both eyes is known as binocular vision, which is essential for depth perception. This is different from monocular vision, which relies on cues from a single eye.
Step-by-step explanation:
The ability to see one image using both eyes is called binocular vision. This type of vision allows for depth perception, which is our ability to perceive spatial relationships in three-dimensional (3-D) space. Binocular vision takes advantage of the fact that our eyes see things from slightly different angles, giving us a more three-dimensional view of the world. Monocular vision, on the other hand, pertains to the cues that require only one eye to perceive depth.
It is interesting to note that we can still perceive depth in two-dimensional (2-D) arrays, such as paintings and photographs, by relying on monocular cues. Our brain is able to make sense of these 2-D visual cues and provide us with a perception of depth, despite the lack of binocular disparity (the slightly different view of the world that each of our eyes receives).
In conclusion, when talking about seeing with both eyes and creating one coherent image, we refer to this as binocular vision, which is also intimately connected with depth perception.
