Abstract
Eyeglasses may include one or more lenses and control circuitry that adjusts an optical power of the lenses. The control circuitry may be configured to determine a user's prescription and accommodation range during a vision characterization process. The vision characterization process may include adjusting the optical power of the lens until the user indicates that an object viewed through the lens is in focus. A distance sensor may measure the distance to the in-focus object. The control circuitry may calculate the user's prescription based on the optical power of the lens and the distance to the in-focus object. The control circuitry may adjust the optical power automatically or in response to user input. The object viewed through the lens may be an electronic device. The user may control the optical power of the lens and/or indicate when objects are in focus by providing input to the electronic device.
