Fluid-filled lenses and actuation systems thereof

摘要

An actuator assembly for an adjustable fluid-filled lens is provided. In some embodiments, the actuator assembly includes a clamp configured to adjust the optical power of the fluid lens module when the clamp is compressed. In some embodiments, a magnetic element is configured to adjust the optical power of the fluid-filled lens. In some embodiments, a plunger changes the optical power of the fluid lens module. In some embodiments, a reservoir is configured such that deformation of the reservoir changes the optical power of the fluid-filled lens. In some embodiments, a balloon is configured to deform the reservoir. In some embodiments, an adjustable fluid-filled lens includes a septum configured to be pierceable by a needle and automatically and fluidly seal a fluid chamber after withdrawal of the needle. In some embodiments, a thermal element can heat fluid within a fluid chamber to change an optical power of the lens module.

主权项

1. An actuator assembly for an adjustable fluid-filled lens, the actuator assembly comprising:
a temple piece having a hollow center fluidly connected to the adjustable fluid lens; fluid located within the hollow center; and a magnetic actuator assembly, wherein the magnetic actuator assembly comprises: (i) a magnetic slider slidably attached to the temple piece; (ii) a magnetic element slidably disposed within the hollow center and magnetically interacting with the magnetic slider; (iii) a pusher arm, wherein the magnetic actuator assembly is configured so that the pusher arm provides a force in an axial direction during the operation of the magnetic actuator assembly; and wherein the magnetic element is configured such that a movement of the magnetic element relative to the temple piece changes the optical power of the fluid-filled lens by increasing or decreasing an amount of the fluid in the adjustable fluid-filled lens.
