<microscopy> A property of lens that causes the image of a plane to be focused into a curved surface instead of a plane. ... The image plane formed by a single lens is naturally curved. While one part of the field will be in good focus, the rest will need refocusing to be sharp. While the eye may partially correct for this, a camera lens will...

This optical defect causes points on an object plane perpendicular to the lens axis to focus on a curved surface rather than a plane. Where light rays passing through a lens causing the lens to focus on a curved plane versus a flat plane. This causes out-of-focus pictures.

a monochromatic aberration of a lens or other optical system in which the focal surface is curved, the refracted image of an object oriented perpendicular to the axis of the lens lying on a curved surface rather than in a plane perpendicular to the axis.
