Variable focus spectacles which comprise, i) a focus module that includes two variable focus lens sections, said sections each including a first fixed plastic lens and an adjustable focus liquid lens, and ii) a second fixed plastic lens that preferably includes most or all of the optical power needed by the intended wearer to correct his/her distance vision. The second fixed plastic lens is preferably attached to the focus module by magnetic attraction.

Actuation mechanism for variable focus spectacles

Номер: WO2006055366A1
Автор: Daniel E. Fedele, Saul Epstein, Stephen Kurtin
Принадлежит: Lane Research Llc

An actuating mechanism for spectacles which include two variable focus lens units. The mechanism mounts on the spectacle bridge; and includes two elongated drive levers mounted near opposite ends of the bridge, each extending toward the other end of the bridge. The free end of each driving lever is connected to its corresponding lens unit through a linkage. The driving levers are caused to rotate simultaneously, but in opposite directions, by a cam that is driven by a sliding member that slides along the bridge. By positioning the sliding member as desired, the spectacles wearer causes the cam to rotate, thereby causing the driving levers to rotate, and both lens units to change focal length.
