What part of eye makes the pupil smaller in bright light and larger in dim light?
The iris is the part of the eye that controls the size of the pupil. In bright light, the iris constricts the pupil to reduce the amount of light entering the eye, while in dim light, the iris dilates the pupil to allow more light to enter and improve vision in low-light conditions.
Which part of the eye becomes narrower in bright light?
The pupil narrows in bright light to restrict the amount of light coming in. In low light conditions it will enlarge to allow more light in for greater vision.
To function efficiently need bright light?
To function efficiently the eye needs bright light. For maximum efficiency the eye needs light to be at a wavelength of 0.555um. The eye can perform efficiently in the dark at a wavelength of 0.510um, but there is a weakness in color.
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 controls the light going into eye?
The pupil controls the amount of light that enters the eye.
What part of your eye needs light to function efficiently?
The part of the eye that reacts to light is the retina.

The part of the eye which decreases in size when a bright light is shone into the eye?
The pupil of the eye decreases in size when a bright light is shone into the eye. This is a reflexive response that helps to regulate the amount of light entering the eye to protect the sensitive retina from damage.
To function efficiently need bright light?
To function efficiently the eye needs bright light. For maximum efficiency the eye needs light to be at a wavelength of 0.555um. The eye can perform efficiently in the dark at a wavelength of 0.510um, but there is a weakness in color.
What part of the eye are opening in the iris through which light passes?
The pupil is the opening in the iris through which light passes into the eye. It dilates in low light conditions to allow more light in and constricts in bright light to limit the amount of light entering the eye.
In a bright light the pupil in your eye will?
When exposed to a bright light, the pupil of the human eye will contract. This action allows less light to come in contact with the lens.
What part of the eye closes and opens to let light in?
The pupil is the part of the eye that dilates and constricts to regulate the amount of light entering the eye. In bright conditions, the pupil constricts, and in dim conditions, it dilates to allow more light in for improved vision.

What is the Response of eye to bright light?
The iris controls the amount of light entering the eyes through pupil. When the surrounding is extremely bright, the iris contracts the size of pupil. This decreases the amount of light entering the eye. This is why when we are suddenly exposed to bright light, the eyes blink and in meanwhile, the iris contracts.
Why do people close one eye in bright sunlight?
People close one eye in bright sunlight to reduce the amount of light entering their eyes and to improve their vision in the bright conditions. This helps to protect the eye from damage and discomfort caused by excessive light exposure.
Which diagram do you think shows an eye in bright light?
