The Stiles-Crawford effect describes the phenomenon where light entering the eye near the pupil's edge is less effective in producing a visual response compared to light entering near the center. This is due to the directional sensitivity of the cones in the retina, which are more efficient at absorbing light that travels perpendicularly to the retina.
