Pupil.
The opening in the eye which allows light to pass through is called the pupil.
Aperture on a camera is the size of the opening/hole in the lens that allows light through. A larger opening lets more light through per second than a smaller one. The size of the opening also affects the depth of field (DOF) in the photograph in the following way: Large opening ------- Small opening Shallow DOF ------- Deep DOF See these links for more detailed info.

The iris of the camera allows more or less light to enter the camera.
opening that lets light in
The iris has an opening, called the pupil, through which light enters the eye.
The word aperture does not apply to the lens itself. In a camera, the aperture is the diameter of the shutter opening which allows light to reach the lens.
A simple camera can be made simply with a light-tight box and a film or sensor, anything to 'capture' the light coming through an opening (lens, pinhole, aperture, etc.) Although this setup is rather rudimentary, it is a camera.

A stage aperture is the opening on a microscope slide that allows light to pass through to the specimen.

A diaphragm regulates the amount of light entering the microscope. Stage opening allows light to pass through the stage of the microscope.
