Adaptive spectacles (20) include a spectacle frame (25) and first and second electrically- tunable lenses (22, 24), mounted in the spectacle frame. In one embodiment, control circuitry (26) is configured to receive an input indicative of a distance from an eye of a person wearing the spectacles to an object (34) viewed by the person, and to tune the first and second lenses in response to the input. |
