Abstract
A user device comprises an imaging device and a controller. The imaging device captures one or more images of a test pattern presented by a display surface through a lens of eyewear device and the test pattern not through the lens in accordance with imagining instructions from the controller. The controller generates imaging instructions and provides the imaging instructions to the imaging device. The controller determines one or more optical parameters of the eyewear device based on the captured one or more images of the test pattern as seen through the lens and the test pattern not seen through the lens. The optical parameters may include an optical power of the lens or an inter-pupillary distance of the eyewear device.
