Fluid filled lenses and mechanisms of inflation thereof

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.

What is claimed is: 
     
         1 . An actuator for a sealed fluid-filled lens comprising:
 a housing;   a reservoir disposed within the housing; and   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, and   wherein the compression arm flexes to compress the reservoir.   
     
     
         2 . The actuator of  claim 1 , wherein the housing comprises a temple chassis and temple cover. 
     
     
         3 . The actuator of  claim 1 , wherein the compression arm compresses the reservoir against a vertical surface of the housing. 
     
     
         4 . The actuator of  claim 1 , wherein the compression arm compresses the reservoir against a horizontal surface of the housing. 
     
     
         5 . The actuator of  claim 1 , wherein the first end of the compression arm is distal to a fluid lens attached to the actuator. 
     
     
         6 . The actuator of  claim 5 , wherein the reservoir is fluidly connected to the fluid lens, and wherein compressing the reservoir delivers fluid to the fluid lens so as to change the optical power of the fluid lens. 
     
     
         7 . A fluid lens assembly, comprising:
 a fluid lens including:
 a front rigid lens, and 
 an inflatable semi-flexible membrane attached to the front rigid lens and having a fluid layer therebetween; 
   a temple cover housing; and   an actuator including:
 a reservoir disposed within the temple cover housing, the reservoir being fluidly connected to the fluid lens, and 
 a compression arm having a first end that is fixed at a pivot point and a second end that is not fixed, 
   wherein the compression arm is disposed adjacent to the reservoir, and   wherein the compression arm flexes to compress the reservoir.   
     
     
         8 . The actuator of  claim 7 , wherein the compression arm compresses the reservoir against a vertical surface of the housing. 
     
     
         9 . The actuator of  claim 7 , wherein the compression arm compresses the reservoir against a horizontal surface of the housing. 
     
     
         10 . The actuator of  claim 7 , wherein the first end of the compression arm is distal to a fluid lens attached to the actuator. 
     
     
         11 . The actuator of  claim 7 , wherein compressing the reservoir delivers fluid to the fluid lens so as to change the optical power of the fluid lens.
