A museum conservator can see fine detail on an artefact held nearby, but writing on a notice across the room is blurred. During an eye test, the suspensory ligaments remain slack when the conservator looks across the room, so the lens stays thick.

A lens thinner in the middle than at the edges, which moves the focal point further back onto the retina.
A lens thicker in the middle than at the edges, which moves the focal point further forward onto the retina.
