Verified step by step guidance

Understand the role of the autonomic nervous system in controlling the pupil size. The sympathetic nervous system is responsible for dilating the pupils, allowing more light to enter the eye, while the parasympathetic nervous system constricts the pupils, reducing light entry.

Consider the physiological response to emotions such as rage. Intense emotions can activate the sympathetic nervous system, leading to pupil dilation.

Analyze the effect of looking at something close to the face. This typically involves the accommodation reflex, which includes pupil constriction to increase the depth of focus, thus reducing the amount of light entering the eye.

Evaluate the state of rest. During rest, the parasympathetic nervous system is more active, leading to pupil constriction and less light entering the eye.

Conclude that feelings of rage, by activating the sympathetic nervous system, would increase the total amount of light coming into the eye due to pupil dilation.
