Our pupils adjust to absorb enough light to see, but not so much that it damages our eyes. So when a bright light is shined in the eye, the pupil closes so that the eye isn't damaged. That's why doctors make you wear sunglasses after they dilate your eyes.

The part of the eye which decreases in size when a bright light is shone into the eye?

What is the consensual reflex of the pupil?

The consensual reflex of the pupil is the simultaneous constriction of the pupil in both eyes when light is shone into one eye. This reflex is controlled by the autonomic nervous system to regulate the amount of light entering the eye and protect the retina.


When a light is shone into one eye what happens to the pupil of the other eye?

When light is shone into one eye, the pupillary light reflex causes both pupils to constrict simultaneously due to the connection between the two eyes. This is known as a consensual response and helps to regulate the amount of light entering both eyes.


In the experiment on the photopupillary reflex what happened to the pupil of the nonilluminated eye?

In the experiment on the photopupillary reflex, when light is shone into one eye causing pupillary constriction (direct response), the nonilluminated eye will also exhibit pupillary constriction (consensual response) due to neural connections between both eyes and the brain. This demonstrates the consensual response component of the pupillary light reflex.

What is the medical term for contraction of the pupil?

The phrase that means that someone's pupils contract when a bright light is shone into their eyes is "pupils reactive" ... they react to the light. If they don't react to the light, they'd be described as "pupils fixed and dilated."

What kind of pattern of light would you get if you shone monochromatic light on a diffraction grating?

If you shone monochromatic light on a diffraction grating it would alternate bright and dark bands. Only white light white light shone through a diffraction grating would produce a band of colors.


Will increasing the amount of light entering the eyes cause the pupil to increase?

Increasing the amount of light entering the eyes causes the pupils to contract. Think about it, if someone shone a flashlight into your eyes, wouldn't you try to shield them?
