Abstract
This disclosure describes, in part, eyeglass systems configured to automatically adjust an optical-power value, or optical power, of lenses of the eyeglass system based on the distance between eyes of a user wearing the eyeglass system and an object that the user is looking at. In some instances, the eyeglass system may determine a degree-of-convergence (DoC) or convergence angle between the left eye and the right eye of the user to determine the distance between the eyes of the user and the object the user is viewing. Further, the eyeglass system may include a power source and lenses that change their optical-power value based on different voltage or current values provided to the lenses by the power source.
