When we actually had to load a roll of film into a very expensive camera and were allowed to take either 24 or 36 pictures on a single role?

Let’s compare the basic principles on how that camera worked as compared to how the human eye functions. both a camera and our eyes have a lens.

Both a camera and our eye have an aperture device. Both receive light and maintain a method of capturing that light. And both have a function to interpret that light into an image. For starters lets look at the lens system.

A camera has a lens on the front surface that (on some models) can be interchanged for varying range of focus.

Our eyes work on a two lens system. The first lens, the cornea is on the outer surface of the eye and can be compared with a cameras lens. In order to adjust focus on a camera, the lens tele-photos meaning it extends in or out in a dynamic function.

In the eye, we have a crystalline lens that also adjusts shape so we can adjust our focus in and out. To adjust light, the camera has aperture settings. While many cameras will do this automatically, true photographers point their camera towards a grey card and get a light reading so they can adjust the aperture setting. Fortunately for us, our eyes adjust aperture automatically.
