Lateral aberration

Lateral: color grows toward the edge

Lateral aberration shifts each color sideways, and the shift grows with distance from the center of the frame. The middle bar above is clean. Each bar outward carries a red edge on one side and a cyan edge on the other.

optical axis: no fringe

Worst at the edge

Seven identical bars. Only the middle one, on the optical axis, is clean. The fringe widens with distance.
