What part of camera lens lets light through?

The iris (technically the diaphragm) lets light from the lens enter the camera. The entire lens can let light fall on the film or sensor. But, much of the time it doesn't do that. An device called an iris makes the hole through which light passes larger and smaller. When all the way open it lets light from the entire lens reach the film or sensor, but it can make the hole smaller and only allow light from a part of the lens enter.

What are the differences between cat eyes with slits and round eyes in terms of their appearance and functionality?

Cat eyes with slits, also known as slit pupils, have a vertical opening that can adjust quickly to changes in light, allowing for better depth perception and night vision. Round eyes, on the other hand, have a circular pupil that lets in more light but may not provide the same level of depth perception. In terms of appearance, slit pupils give cats a more predatory look, while round eyes are more common in humans and other animals.
