Abstract
Systems and methods regarding spectacle systems are provided including base lens units and attachable lens units. A spectacle system may include a base lens unit with a first lens, a frame configured for wearing the base lens unit on a user, and a first attachment mechanism. The spectacle system may also include an attachable lens unit with a second lens and a second attachment mechanism configured to join with the first attachment mechanism. A communication mechanism may also be included that is configured to communicate data, instructions and/or electrical power between the base lens unit and the attachable lens unit. Either or both of the first lens and the second lens may include an electro-active lens. The attachable lens unit may include a variety of additional functions such as an electronic display, a camera, an active shuttering lens, and an active polarizing lens, which may also be powered by the base lens unit.
