Abstract: Eyewear providing dynamic focus. The eyewear includes two lenses, a mechanism for detecting a near object viewed by a user of the eyewear and a mechanism for dynamically changing a focus of the lenses. The lenses change focus to a near focus when a near object is detected. The eyewear may be eyeglasses or contact lenses.

Abstract: Glasses having a frame and two lenses. Each of the lenses is attached to the frame. A distance measurement module determines a distance to an object viewed from the glasses. The glasses also include a motion control module for raising and lowering the first and second lens and a controller for determining when it is appropriate to raise the first and second lenses. When the controller determines that it is appropriate to raise the first and second lenses to a raised position, the controller directs the motion control module to raise the first and second lenses. In one embodiment, each lens has a plurality of lens sections which may provide different types of focus. The lenses may be raised or lowered appropriately to allow view through one of the lens sections.
