摘要:
An optical and mechanical design of a sealed, non-round fluid-filled lens capable of providing variation of optical power. The fluid lens includes at least three optical components: at least one mostly rigid optical disc, at least one mostly flexible optical membrane and a layer of a transparent fluid that is in communication via a fluid channel with a reservoir of excess fluid contained in a reservoir that can be accessed to augment the fluid volume inside the fluid lens to change the power of the fluid lens. The fluid lens is capable of providing correction of spherical and astigmatic errors, and utilizes contoured membranes to minimize image aberrations.

摘要:
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.

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.
