The pinhole camera has no lens. The human eye has a variable-focus lens.
The whole thing. The Lens
In a camera, the lens is fixed - focusing is done by moving the lens forward or backward to get a sharp image. In the human eye, muscles surrounding the eyeball 'distort' the lens to change its focal length.
focusing lens of the eye....
A camera eye is an eye with a crystalline lens that focuses light. It is found in squid, octopi, and vertebrates. This is similar to the lens arrangement of a camera.
There are a few camera lens types such as : a wide angle lens (used to capture a larger area than the area visible by a human eye), telephoto lens (opposite of wide angle), panoramic lens and so on.

I think a pinhole camera is similar to the human eye because like the pinhole camera when it sees something it reflects the image but it is an inverted image. With the human eye the brain corrects it and turns it the right way up. The pinhole cameras image is not corrected because it does not have a lens.
A convex or converging lens is found in the human eye.
