________ is a sensory process in which the muscles of the iris contract in response to low illumination levels.

Question

Quizplus · Accepted Answer

Dark adaptation is the process where the eye adjusts to low light conditions, which includes the dilation of the pupil to allow more light to enter the eye, not specifically the contraction of the iris muscles. However, the question's description inaccurately describes dark adaptation as involving the contraction of the iris muscles, which is more directly related to the process of the pupil adjusting size in response to light levels. The correct term for the process involving the iris muscles contracting or relaxing to adjust the pupil size in response to light is not explicitly listed among the options, leading to a misunderstanding in the explanation. The process described in the question seems to conflate elements of how the eye adjusts to light levels, but none of the provided options accurately capture this process.
