Dynamic zone plate augmented vision eyeglasses

An apparatus for generating a retina image by modulating optics in a retina display, comprising:

• a processing system configured to:
• form a plurality of zone plates in a liquid crystal using electric fields, each zone plate having a center, wherein the centers are aligned along a first axis of the display;
• and
• move, by repositioning electric fields through the liquid crystal, the plurality of zone plates in a first direction along a second axis of the display different from the first axis of the display, while maintaining alignment of the centers of the plurality of zone plates along the first axis.

A computer program product for generating a retina image by modulating optics in a retina display, comprising:

• a computer-readable medium comprising code for:
• forming a plurality of zone plates in a liquid crystal using electric fields, each zone plate having a center, wherein the centers are aligned along a first axis of the display;
• and
• moving, by repositioning electric fields through the liquid crystal, the plurality of zone plates in a first direction along a second axis of the display different from the first axis of the display, while maintaining alignment of the centers of the plurality of zone plates along the first axis.
