Abstract
A mobile device lens assembly having an electrically activated lens component with an electro-optic portion is disclosed. More particularly, embodiments of the mobile device lens assembly include the electro-optic portion and an interlock feature to engage a second lens element. The second lens element may have an interlock surface, which when engaged or mated with the interlock feature of the electrically activated lens component, may maintain alignment of the lens components along an optical axis. Other embodiments are also described and claimed.
