Question

Quizplus · Accepted Answer

When it is dark, the pupil dilates to allow more light into the eye, which can help improve vision in low light conditions. Therefore, Amanda's ability to see in the dark after 20 minutes is most likely due to her pupil dilation. Visual afterimages refer to seeing a lingering image after looking at a bright light or object, retinal disparity is the difference in image location between the two eyes that helps with depth perception, and color constancy refers to the ability to perceive colors consistently under different lighting conditions. None of these processes are directly related to improving vision in low light.
