Human vision is created from the eye or the brain?or both work together?

Question

I appreciated professional answer...

Answer 1

the eye picks up the light and turns it into signals and send it to the brain, which in turn interprets the signal and produces an image

Answer 2

The answer from your choices is BOTH WORK TOGETHER.

However, the amount of image analysis done inside the retina is very extensive.

The reception in the eye is like a camera only in that the lens focuses an image on the retina. The retina is not even flat like the CCD or CMOS sensor in a camera.

In a camera, the light values of the individual pixels are transmitted to a processing unit as RAW data, and then the "brain" of the camera extracts meaningdful data, and then compresses the information into a JPEG or other type of image.

In the human eye, the cells of the retina and early optic nerve correlate and analyze data long before it is sent to the brain. The signals sent to the brain are not about individual pixels, they are about measurements like straightness, roundness, fuzziness. The edges of the field of vision have almost no resolution, but are extremely sensitive to motion. Our sensitivity to resolution is limited to a yellowish channel called Y.

All this pre-processing allows the brain to do minimal work in using the eye's data.

In fact, the whole idea of JPEG encoding is to remove information that the eye does not send to the brain.

Answer 3

Some people consider the eyes to be a part of the brain. But the 'classical' answer is they both work together. The retina of the eye converst light and wavelength information to neural impulses which the brain then deciphers as an 'image'.

Answer 4

For the complete vision of a person brain and eye both will work together.

Answer 5

Eye collects information and brain interprets it. Two eyes see two images but brain interprets them only as one object. Brain also stores a picture of what we see. So we can recapitulate the picture after some time or with eyes closed. Visual hallucinations occur when eyes see nothing but brain interprets a non existing image. Eyes and brain work together.

Answer 6

The eye contains two types of photoreceptors, or cells that react to light. The type called cones react to different wavelengths of light, and function well in ample light. There is one cone for each of three ranges: yellow-green, blue-green, and blue-violet. Rods are more sensitive to light, and function well in low light, but do not detect colors. When these cells are activiated by a suitable stimulus, they send nerve impulses to the brain. The brain then synthesizes what you know as a visual image. So it is the eye and the brain working together.

Answer 7

Actually, the eye is considered to be part of the brain, not a seperate organ. So vision comes from a part of the brain called the eye.

Answer 8

The eye sends the image to the brain, where the brain interprets the image.
So they both work together

Answer 9

They both work together... You see with your eyes, but the image is considered "upside down"... then your brain takes the image and makes it "right side up".

Your eyes kinda work like a telescope (i think its that one) where there are two mirrors.... one on top (image is up-side down) and the one on the bottom views that same mirror but then the image is made right (right-side up)

Answer 10

It is both. A person can have perfectly healthy eyes and be blind because of a brain lesion. This is known as "cortical blindness." Conversely, trauma to the eyes creates normal blindness
