An eyewear device presents, via an image display, an initial displayed image. The initial displayed image has an initial field of view corresponding to an initial head direction or an initial eye direction. Eyewear device detects movement of a user of the eyewear device by: (i) tracking, via a head movement tracker, a head movement of a head of the user, or (ii) tracking, via an eye movement tracker, an eye movement of an eye of the user of the eyewear device. Eyewear device determines a field of view adjustment to the initial field of view of the initial displayed image based on the detected movement of the user. Field of view adjustment includes a successive field of view corresponding to a successive head direction or a successive eye direction. Eyewear device generates a successive displayed image based on the field of view adjustment and presents the successive displayed image.

In an embodiment, a modular augmented reality display is provided that incorporates prescription eyewear that can be used separately by the wearer. In an embodiment, an image is generated from a removable display attached to the eyewear and directed into the edge of a prescription lens, which acts as a waveguide. The image is internally reflected within the prescription lens, and is directed to the wearer by an image combiner embedded within the prescription lens. In an embodiment, the augmented reality display includes a wearable belt pouch that includes a battery and support electronics connected to the eyewear so that the weight on the eyewear is reduced.

Apparatus and methods are described including a corrective optical element having a thickness and/or a curvature that is different in different regions of the corrective optical element, such that the corrective optical element is configured, upon being adhered to any one of a plurality of differently-shaped optically-corrective single-vision lenses, to change a focal length of the optically-corrective single-vision lens differently in different regions of the optically-corrective single-vision lens. The corrective optical element is shapeable such that the corrective optical element can conform with a shape of any one of the plurality of differently-shaped optically-corrective single-vision lenses. Other applications are also described.
