This is based on the fact that at 20/20 vision, the human
eye is able to resolve
the equivalent of a 52 megapixel camera (assuming a 60° angle of view). However, such calculations are misleading. Only our central vision is 20/20, so we never actually resolve that much detail in a single glance.
Why the human eye is compared with camera?
Both eye and
camera can control the amount of light that enters
, in the eye, it is controlled by iris, and in-camera it is controlled by an adjustment in an aperture. Both eye and camera can focus on a single object and both can focus on the large scape.

Which is better human eye or camera?

Is eye the best camera?
Most current digital cameras have 5-20 megapixels, which is often cited as falling far short of our own visual system. This is based on the fact that at 20/20 vision, the human eye is able to resolve the equivalent of a 52 megapixel camera (assuming a 60° angle of view). However, such calculations are misleading.
How many megapixels is a human eye?

about 3 miles away

What do eyes and cameras have in common?
How are an eye and a camera similar? An eye and a camera both have

Also, the space between the cornea and the lens is filled with a gel-like fluid called the aqueous humor. All of these layers form a
watertight barrier
that seals off the inside of the eyeball from the outside world.
What lens is closest to human eye?
The
50mm lens
is closest to the eye and thought to provide the natural field of view on a full-frame camera, and in terms of DX body, the 35mm which is henceforth the closest to a 50mm is your natural eye field of view lens.
What part of the camera is like the lens?
Light is focused primarily by
the cornea
— the clear front surface of the eye, which acts like a camera lens. The iris of the eye functions like the diaphragm of a camera, controlling the amount of light reaching the back of the eye by automatically adjusting the size of the pupil (aperture).
