The eyeball is called the eye or the eyeball, no other scientific names for it.
And what do I call it? An e y e b a l l . :)
The hole in the center of the iris through which light can pass is called the pupil.
the name of the hole that allows light to go through into your eye is: pupil
They are hollow so light can pass through to the retina, so you can see. The pupil is the opening in the iris. To ask why the eyes' pupils are hollow is analogous to asking why a donut hole is hollow.
no, because your iris lets light in, and without the hole, you wouldn't get any light, and all you would see is dark.
The iris has an opening, called the pupil, through which light enters the eye.
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
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.
Retina- light image is focused on the retina, and it contains the photosensitive receptor cells Pupil- the opening of the eye. The size of the opening is regulated by the iris Iris- pigmented part of the eye (gives people their eye color). The iris is composed of smooth muscle and controlled by reflex.
iris
Light enters the eye through the cornea, which is the clear outer layer that acts as a protective barrier. The cornea then helps focus the light before it passes through the pupil, the opening in the center of the iris that controls the amount of light entering the eye.
The pigmented portion of the eye with a rounded opening through which light passes is the iris. The iris controls the size of the pupil, which regulates the amount of light entering the eye.
Light first enters the eye through the cornea, the clear outer covering of the eye that helps to focus light. The cornea then bends the light and directs it through the pupil, the black hole in the center of the colored iris.
