An edge is perceived based on the contrast between two adjacent areas of the visual field. While lines, contours, and separations can contribute to the perception of an edge, it is ultimately the difference in brightness, color, or texture between the adjacent areas that gives rise to the perception of an edge. The retina is not directly involved in this process, as edges are processed in the visual cortex rather than in the retina itself.
