Abstract
An imaging device comprising a first camera with a controllable focus is provided. The imaging device is operative to detect that a user of the imaging device intends to capture an image of an object using the first camera, control the focus of the first camera to assume a target focal length, and capture the image. The target focal length is derived based on a measured accommodation of an eye lens of the user. Further, a contact lens comprising an eye-accommodation detector and a communications module is provided. The contact lens is operative to measure an accommodation of an eye lens to which the contact lens is attached, and transmit, to an imaging device comprising a first camera with a controllable focus, information pertaining to the measured accommodation of the eye lens and/or a focal length of the eye lens corresponding to the measured accommodation.
