Abstract

Embodiments are generally directed to automatic focus prescription lens eyeglasses. An embodiment of an apparatus includes one or more variable focus lenses coupled; one or more actuators to change the focus of the variable focus lenses; and one or more focus distance components coupled to detect a focus distance of one or more eyes of a user of the apparatus. The one or more actuators set a focal distance of each of the one or more variable focus lenses, a focal distance setting for each of the one or more variable focus lenses being determined in response to the focus distance of the one or both eyes of the user; and the focal distance setting for each of the one or more variable focus lenses includes adjustment for a vision prescription of the user.
