How many pixels is the human eye?

The human eye is absolutely not as fine as a high-precision camera in pixels.

The human eye can be said to be an autofocus camera, but because the focal length of the eye is too short, it can't see the distant scenery clearly. The optimal sight distance of human eyes is about 10- 100 cm. If you shoot an object at this distance, it is equivalent to more than 300 dpi pictures.

However, if the eyes are shot above 10 meter, the resolution is low.

If you look at a painting at a distance of 10 meter, the number 10 is definitely not clear, but if you take pictures with a good camera, the number 10 is definitely clear. It can be seen that human eyes are not as good as cameras.
