It happens when light rays passing through the edge of a lens focus differently than rays passing through the center. In eye care, it is discussed in relation to the cornea, the natural crystalline lens, and artificial intraocular lenses. It is commonly measured with wavefront testing and considered in refractive surgery planning and lens design."}
