The image should form on the retina. More specifically in the fovea centralis of the macula of the retina.

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.
What is is the nerve tissue at the back of the eye which receives the image that has been formed by the cornea the pupil and the crystalline lens?
retina
The colored part of the human eye is the A pupil C cornea B retina D iris?
iris
What Is the nerve tissue at the back of the eye which receives the image that has been formed by the cornea the pupil and the crystalline lens.?
That would be the retina.
Where does the lens on a pupil focus light?
Onto your retina. Onto your retina.
How does your eyes see and what does it have to see clearly?
How the eye sees begins with light rays that reflect off objects and travel through the eye's optical system. These rays of light are refracted and focused into a point of sharp focus on the retina. If it is not on the retina, vision quality is diminished. The retina is the tissue that lines the inside of the back of the eye, where light-sensitive cells capture images. These images are then sent to the brain for interpretation via the eye's optic nerve. Lastly, the eye's pupil widens or constricts to control the amount of light that reaches the retina. In bright conditions, the pupil constricts. In dark conditions, the pupil widens.
Can mace blind you?
Yes! It has a highly toxic chemical in it called Argonoxide which can cause the inner retina to dry and become useless. This retina allows you to percieve crude images. Without it, light particles can not enter the pupil.
How does the iris adjust to the amount of light that enter he?
The iris is a muscle located behind the cornea of the eye. It adjusts the size of the pupil to control the amount of light entering the eye. In bright light, the iris contracts to make the pupil smaller, limiting the amount of light that reaches the retina. In low light, the iris relaxes, making the pupil larger to allow more light into the eye.
What tunic concerns image formation?
The Vascular Tunic. Formation of images on the retina include three processes: Refraction of light rays; accommodation of the lens; and constriction of the pupil. The pupil and lens are housed in the Vascular Tunic.
Which gathers the light that enters the pupil?
The retina.
Which bit of your eye is the retina?
the black pupil
How is the Nerve impulse responsible for the pupil becoming smaller?
Pupil is a window for the light to enter our eyes. When we are in a dim light a nerve impulse is generated to the brain to enlarge the pupil. Size of pupil is managed by the iris (coloured part of the eye). If excessive light is there, the pupil shrinks to a smaller size so that the eye's not damaged esp. the retina where the image of objects are formed
