Zusammenfassung:Variable focus optical devices, in particular lenses, can include a cavity at least partially defined by a flexible member ( 2 ), which may be retained between engaging portions of a frame member ( 8 ) and a ring member ( 12 ), such that a peripheral region of the membrane is caused to change direction, more than twice. The engaging portions of the ring and frame may be high-friction surfaces. In addition, methods of filling a cavity of a lens with transparent fluid, methods of adjusting the pressure of fluid in the cavity, and methods of sealing such a cavity are described, as well the use of such lenses in adjustable spectacles.
