Is a camera very much like a normal (i.e. perfect vision) eye? If we wear lenses, we will like the camera be able to 'see' focused images very far away or very close which is like zooming in or out with the camera.
Some people with eye problems like myopia cannot see a focused image beyond their near point so they see a blurred image. However, I have noticed my camera never register a blurred image no matter if zoomed in or out. Why is this?
Why does a camera always register a focused real image on the film no matter how its zoomed but the human eye is subject to defects like myopia, even though the camera and eye are very much alike?
Note: I understand that the human eye is unable to zoom because it recquires multiple lenses whereas we only have one but normal eyes can focus near and close objects because our single lens is able to contract and expand.
