The method comprises utilizing optical and electrical sensing apparatus to detect the physiological change of viewer's eye without viewer's active participation or physical action, and retrieving the intended focus depth information of the viewer from such physiological information to update the visual impression perceived by the viewer that matches the intended focus depth, to achieve a re-focusable vision. The sensing apparatus includes both “glass” type and “contact-lens” type of see-through substrates that contain optical and electrical components that are necessary for obtaining the physiological information of viewer's eye and controlling the visual impression that the viewer perceives."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus to produce re-focusable vision with detecting re-focusing event from human eye","description":"The current invention relates to the method to achieve re-focusable vision, including re-focusable stereo vision, with detecting the re-focusing event from a human eye.
