Individually, each eye sees a two dimensional image projected on your retina...

Your brain takes the simultaneous image from both eyeballs, and uses the stereoscopic vision, and a whole lot of triangulation to get an awareness of the three dimensional space in front of it.

So 1 eye = two dimensional sight, 2 eyes together = 3D, and your brain does the math to make it happen

Technically, each individual human eye gathers light from a single side of what is being observed, and the brain composes this information into a two-dimensional image, like a photograph.

However, with two eyes, two slightly different images are combined to create a sense of depth and allow a judging of difference. Even a single eye's lens can alter its focus from near to far, allowing a gauge of distance to an object.

must humans have two there are humans with 4, 3 (Siamese twins), 1, or 0 eyes too, but that is very rare more than 99% of the humans have 2 eyes, so you can safely assume that the human race possesses 2 eyes also, if you meant the word ears(i often get those mixed up too!) the same applies!! its a really handy trick to remember that most humans have so many ears and eyes, that when you multiply them, or add them up, you get the same number !!! (namely 4!)

The human eye sees things in Binocular vision, the brain interprets the image as a 3D image.

each of the human eye lens forms a 2d vision of each point in front of the eye since an image of every point of the length,breadth and height of an object is seen by the eye a complete 3d image is interpreted by the brain. adding to this is the binocular vision of the two human eyes

A single eye sees in two dimensions, only when you look through both eyes do you see the depth perception. You need both eyes to differentiate between distance and size.

Three dimensional. Each eye views from a different angle allowing depth of field perception.

both eyes see a seperate image from a slightly different perspective and the brain merges these imagine into one that gives the us depth in our vision.

3. The offset between two receptors makes stereoscopic vision possible.
