1. An optical article comprising:
an optical lens shell having an internal surface and an extemal surface, wherein:
the optical article further comprises a support element mounting the optical lens shell, disposed in a fixed position, and movably mounting a moveable element between a first position and a second position, wherein in the first position the moveable element is against the optical lens shell, wherein in the second position the moveable element is released from the optical lens shell,
the optical article further comprises a first sealed cavity, placed between the moveable element and the internal surface of the optical lens shell, coupled to a fluid inlet adapted for adjusting an amount of fluid in the first sealed cavity,
the optical article is switchable between a first configuration and a second configuration,
in the first configuration, the moveable element is passively held in the first position, and
in the second configuration, the first sealed cavity is filled with a predetermined amount of a first fluid altering propagation of visible light and the moveable element is held in the second position by pressure exerted by the first fluid in the first sealed cavity,
wherein the optical article is switchable between the first configuration and a third configuration,
wherein in the third configuration, the first sealed cavity is filled with a predetermined amount of a second fluid, and the moveable element is held in the second position by the pressure exerted by the second fluid in the first sealed cavity, and
wherein the second fluid alters the propagation of visible light differently than the first fluid.
