Which part allows light into eye?
The Lens. The Iris controls the amount of Light reaching the Retina.
What are the parts of the eye that keep light out?
If considered part of the eye, the lids can prevent most light from entering the eye. Otherwise, the amount of light allowed inside the eye is primarily controlled by the Iris. The Iris surrounds the pupil which is literally a hole. The Iris can make the pupil smaller (constrict) or make it larger (dilate). The larger the pupil is, the more light enters the eye. The muscle movements responsible for contraction or dilation are "automatic" or involuntary. RE: prior answer of "Retina controls the amount of light let in and let out". The amount of light reaching the retina affects the Iris. The retina is at the back of the eye and is where light is changed into nerve signals. If those nerve signals indicate that there is a lot of light entering the eye, the iris will constrict making the pupil smaller. The opposite happens if the nerve signals indicate that there is very little light.
What controls the thickness of the lens to help focus light on the retina?
It is detected by the retina and 'thickness' varies as it is a reflex action; it cannot be controlled. Basically, 'you' cause it without knowing so.
What is the function of a diaphragm in a camera?
It controls the amount of light that reaches the film.
What is the function of the diafragm in a microscope?
it controls the amount of light let into the slide.
What is 'irie'?
The colored, and muscular ring around the pupil in your eye. It narrows in bright light and widens when light is dim.It also controls the amount of light reaching the retina
Which part allows light into eye?
The Lens. The Iris controls the amount of Light reaching the Retina.
What is the light-sensitive inner layer of the eye?
The retina converts light to electric signals used by the occipital cortex of your brain, that is sight. The iris is the black looking part of your eye the expands and contracts to control the amount of light reaching your retina.
What controls the amount of light that enters the eyes?
The pupil contracts or expands (dilates) to regulate the entry of light to the retina in the eye.The iris or colored part of the eye is what controls the diameter of the pupil by covering or uncovering it.
What is the layer of photoreceptors?
the retina contains the rods and cones which sense the amount of light and different colors respectively.
What two parts of a camera controls the amount of light reaching the film?
The Shutter and the Aperture are the two controls the Shutter is used to control how long the Film is exposed for and Aperture is used to control how much light is let in
What structure controls the amount of light that gets in the eye?
Iris controls the amount of light entering into the eye.
What Controls the amount of light entering the microscope adjust what part?
the diaphragm controls the amount of light entering the microscope
Does the lens of the eye control the amount of light that strikes the retina?
False :)

What controls the light going into eye?
The pupil controls the amount of light that enters the eye.
Where in the retina is the light focused nearsighted?
The retina is a light sensitive layer located at the back of the eye and is used by near and far sighted people.The lens of the eye controls how images are projected onto the retina and this is what causes sight problems such as near and far sight.
