Claim 0:
1. A wearable optical device configured to increase a Resolvable Object Distance Range (RODR) for a plurality of objects located along a visual angle distance by optically pushing a nearby object further away along the visual angle distance thereby reducing focusing demands when a user is visually fixating on a nearby one of the plurality of objects, and wherein the optical device includes:
a negative refractive element having an optical axis; and
a positive refractive element configured to be aligned with the negative refractive element along the optical axis;
wherein the negative refractive element and the positive refractive element are separated from each other along the optical axis by a separation space and at a separation distance suitable for mounting on a spectacle; and
wherein a surface of a non-central zone of at least one of the negative refractive element and the positive refractive element is a Fresnel surface, and wherein the separation space is substantially filled by a non-air intermediate media with a refractive index lower than that of the at least one of the negative refractive element and the positive refractive element.
