Question

What is the consensual response (the response of the left eye)?

Answer 1

Answer:

Constriction of pupil of left eye in response to entry of bright light in right eye.

Explanation:

The consensual response is a reflex response towards the intensity of light. When the right eye is exposed to the bright light, there is constriction of its pupil mediated by iris to regulate the amount of light entering the eye ball. However, at the same time, the pupil size of the left eye is also reduced to limit the amount of light entering the eye. This response of the left eye towards the exposure of the right eye for bright light is called consensual response.
