Abstract: A fluid lens assembly including a front rigid lens, a semi-flexible membrane that is adapted to be expanded from a minimum inflation level to a maximum inflation level, and a fluid layer therebetween. The front lens of the fluid lens assembly is configured to have a negative optical power. In an embodiment, the fluid lens assembly may be configured to have an overall negative optical power when the membrane is expanded to the maximum inflation level. In an embodiment, the fluid lens assembly can be configured to have an overall negative optical power when the membrane is expanded between the minimum inflation level and the maximum inflation level.

Abstract: In an embodiment, a hinge for a fluid-filled lens assembly includes a base having a first end configured to connect to a temple arm of the lens assembly and a second end configured to connect to a frame of the lens assembly, wherein the base includes a gap that is shaped to allow for tubing to pass from the first end to the second end of the base. In an embodiment, the first end of the base includes a cammed surface configured to engage a surface of the temple arm. In an embodiment, the first and second ends of the base are configured to flex around a rotation axis of the hinge.

Abstract: An actuator for a fluid-filled lens including a housing having a first and second end; a reservoir disposed within the housing is disclosed. In an embodiment, the actuator further includes a compression arm having a first end that is fixed at a pivot and a second end that is not fixed such that the compression arm flexes to compress the reservoir.

Abstract: An actuator for a fluid-filled lens including a housing having a first and a second end; a reservoir disposed within the housing. In an embodiment, a slider is slidingly disposed within the housing and disposed adjacent to the reservoir. In an embodiment, the actuator further includes a compression arm having a first end that is fixed and a second end that is not fixed, wherein the compression arm is disposed adjacent to the reservoir. Sliding the slider from one end of the housing to the other causes the slider to push the second end of the compression arm so as to compress the reservoir. In an embodiment, the slider includes a first end having a wedge shape configured to compress the reservoir. Sliding of the slider from one end of the housing to the other causes the first end of the slider to compress the reservoir.

Abstract: Disclosed are apparatuses and manufacturing methods for a fluid filled lens reservoir system. The eyeglass reservoir system includes a temple piece having a cavity, a bladder positioned within the cavity and configured to repeatedly compress and relax, the bladder being made of a flexible material, and a connecting tube coupled to an inlet port of a lens module and to the bladder, configured to carry a fluid between the bladder and a fluid filled lens cavity of the lens module. The eyeglass reservoir system further comprises a compression arm contacting the bladder and configured to transmit force from an actuator to the bladder to cause movement of the fluid between the bladder and the connecting tube. The bladder and connecting tube are made of a flexible material such as polyvinyledende difluoride. The connecting tube further comprises a flared end configured to couple to the inlet port of the lens module.
