If both eyes can see one object then why do we get illusion of only one object?why dont we see two objects?

Question

e.g. if there is a tower we can see it with both eyes independently i.e.image formation in one eye is independent of other.So with both the eyes opened why do we get to see only one tower and not two one for each eye

Answer 1

The two images are compiled by the brain to create depth perception. Without two eyes everything would look much more flat and it would be difficult to calculate distance. You could just say its "built in software" in the brain that compiles the two images. If you cross your eyes you can fool the mechanism a little bit and then you are seeing two separate images that cannot be compiled.

Answer 2

Both eyes are pointed at the same object. If something's too close for both eyes to point at the same thing, the object gets out of focus.

To test this, hold a finger at arm's length. It's in focus. Then move it to within a few inches of your face. It's too close for both eyes to look directly at it, so you see two images of that finger.

By the way, the fact that we have two eyes allows us to have depth perception. People with only one functioning eye have a hard time telling how far away something is.

Answer 3

As long as the focus point is the same for both eyes, your brain will do its best to combine them and interpret a 3D image of the object. But you can just as easily look "past" and object and if you concentrate you'll notice that the other item is now doubled on the edges, with your brain still trying to create a new 3D image of the area that crosses.

The old kids trick is to point both hands at each other so that your pointer fingers touch. Look at the spot where they touch, then look past that spot to a distant location. Your brain creates a floating finger-let between them. If you separate your fingers apart, it even floats. It look perfectly 3D and real enough (just out of focus). That's your brain using visual input to simulate a 3D object, in action.

Now, can you wiggle your eyeballs on command?

Answer 4

Because our eyes are close enough together that this doesn't really happen in a properly working person. Plus there is a lot of communication between the brain and the eyes to process the images we see.

Answer 5

It is the job of the neurons which when seen through the two eyes but the picture which we see is registered in brain is only one picture so only whn we see a object with the two eyes shows u only one picture and one thing is human brain is 100000 times faster the super computer created by microsoft.........

Answer 6

The brain combines the images from both eyes and uses the information to create a wider picture with peripheral vision and depth perception.,

Answer 7

What we perceive is the 3D virtual universe in our own minds.

Your mind contains a virtual 3D universe which is an approximation of the real universe (or vice versa, depending on your religious belief). You also have virtual eyes in your mind which look at the virtual universe. By comparing what your virtual eyes see to what your real eyes see, you detect discrepancies. Then you adjust the content of your virtual universe to make the virtual eyes see the same images that your real eyes see.

So you don't actually see the real eye's image directly. Instead, you see your own 3D virtual universe.

Answer 8

Because your brain knows how to put 2 images together to see in 3-D. If you bring something close enough to your face, your brain gets confused and you see double. Also, if you get hit hard enough, your brain goes haywire and you see double (hence the "how many fingers am I holding up?" question)

Answer 9

we get one image as we have binocular vision where the images are made independently and brain merges and interpret them one , image lies at the focus where the two images superimposes but brain interprets it in 3-D image.

Answer 10

Two words: depth perception.
