Abstract
Various implementations disclosed herein include devices, systems, and methods that determine a lens characteristic of an attachable lens using reflections. In some implementations, a method can include producing a pattern of light using an arrangement of light sources. Then, reflections are detected in an image obtained via an image sensor, the reflections corresponding to light from each of a plurality of the light sources reflecting from a surface of an attachable lens. In some implementations, a lens characteristic of the attachable lens is determined based on the detected reflections and a 3D spatial relationship between the image sensor and the plurality of the light sources. In some implementations, the lens characteristic is a prescription, and content is provided at the electronic device based on the prescription, where the content is viewable through the attachable lens.
