Optical system with localized magnification

A method for creating a zone of interest in an optical image, the method comprising:

• a. providing an optical system with an optical axis, the optical system comprising a plurality of optical elements configured to create an optical image in an image plane;
• and
• b. providing, on at least one of the plurality of optical elements, at least one feature of localized optical power making the at least one optical element non- symmetrical with respect to the optical axis;
• such that an optical image formed by the optical system and the at least one feature of localized optical power includes at least one zone of interest that is non-symmetrical with respect to the optical axis, the at least one zone of interest being located at a predetermined distance from the optical axis in a first direction and having a first magnification, and
• such that the optical image formed by the optical system and the at least one feature of localized optical power has a reference region located outside the zone of interest, the reference region being located at the predetermined distance from the optical axis in a second direction different than the first direction and having a second magnification different than the first magnification,
• wherein a half field of view of the optical system in the first direction is the same as a half field of view of the optical system in the second direction.
