The aperature can control the amount of light that comes into the camera just like the pupil of the eye.

What part of the eye is most like an aperture of a camera?
The iris is like the aperture part of a camera, which used to also be called the iris.
What part of the camera corresponds to the lens of the eye?
The focusing lens of the camera
How is a pupil of a human structured?
The pupil is the center round black part of the eye. This is where the light enters into the retina. The human pupil works much like the aperture of a camera.
How is the aperture of the camera like a pupil?
Because its diameter can be changed to alter the light level on the sensor behind it. In a camera this is done by altering the f/number. In the eye it occurs via an automatic physiological response.
Is it the lens or iris that acts like the eye in a camera?
The iris acts like the aperture of a camera lens.
Why do pupils in your eyes grow larger in the dark?
Just like the aperture on a camera, your pupil dictates how much light is let into your eye. So when you shine a light in your eye your pupil gets tiny, and in the dark your pupil gets large to let as much light in as possible so you can see better.
What part of your eye is like the diaphragm of a camera?
It is identical in action to the iris in your eye, it widens and narrows to allow only the required amount of light through the aperture hole/pupil
Why does astigmatism affect your night vision?
At night, the pupil dilates to let in more light. Astigmatism is a distortion in the cornea that causes different focal lengths for light passing through different parts of the cornea into the lens. With a small aperture (constricted pupil), the differences do not cause noticeable blurring; just as in a camera, a small aperture gives greater depth of field. At night, when the aperture is larger (dilated pupil), the eye has less depth of field, so the imprecise focal length of the eye causes the image to be noticeably blurred.
What are the similarities between a camera and a human eye in terms of the image formed?
Both cameras and eyes have lenses that can focus and will project an image ( upside down ) of what they are looking at, and the Pupil from an human eye can expand or contract to adjust the amount of light that enters, this is the same as the shutter of a camera.
What is the pupil in the human eye and what does it do?
The pupil is an opening into the center of the eyeball, where the retina (visual receptor layer) is located.The pupil is located in the front center of the eyeball, and its size (aperture) is controlled by the iris or colored part of the eye. The pupil is just behind the cornea, or lens, that focuses light on the interior surface of the eye (the retina).
What is The difference between pupil and iris?
The iris is the coloured part of the eye. It's typically brown or blue, but other colours like green or grey are possible. The pupil looks like a black dot in the centre of the iris. It can dilate (get wider) and contract (get smaller). The size of the pupil changes depending on how bright the light is. If you are in a very bright room, or in bright sunlight, your pupils will be very small. This is because not much light needs to be let in to the eye for it to be able to see well. In a dimly-lit room your pupils will be bigger, to let as much light into the eye as possible.
What is the outer portion of the eye through which light passes to retina?
That part is called as pupil. Through this aperture the light goes in to retina.
