Does each eye take in something different or exactly the same?

Question

Does each eye take in something different or exactly the same? Are they linked to the different sides of the brain or does that happen after each image from each eye is combined?

If different things are processed on different parts of the brain is your brain processing the combined image of both eyes or each eye's image seperatly?

If our brain is taking in two images and combining it into one how could we test if it's taking in different information from each eye independently?

Answer 1

The images are slightly different, because of parallax. They are combined in the visual cortex, a structure at the back of the head. The cortex is a programmable logic array, implemented with neurons rather than transistors as an electronic engineer might do. During the first few months of life, the array is programmed by comparing the images; neurons useful for the combining process survive, while the others die off.

Answer 2

Two eyes capture slightly different images and sent to the brain separately. The brain process it to create a 3D image.

Since brain is a complex processor, it can handle both images at the same time and generate a understandable signal.

If you use a single eye, you will see 2D images.

Answer 3

each eye takes in something different. the effect of this is depth perception. to test it, try to hit a baseball with one eye closed.

the reason for this is that your eyes are physically seperated from each other by the bridge of your nose, and are therefore different distances and angles from the object in the field of vision.
