FLUID FILLED LENSES AND MECHANISMS OF INFLATION THEREOF CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to U.S. Provisional Patent Application No. 61/251,819, filed October 15, 2009, which is incorporated herein by reference in its entirety. BACKGROUND Field [0002] Embodiments of the present invention relate to fluid-filled lenses and in particular to variable fluid-filled lenses. Background Art [0003] Basic fluid lenses have been known since about 1958, as described in U.S. Pat. No. 2,836,101, incorporated herein by reference in its entirety. More recent examples may be found in "Dynamically Reconfigurable Fluid Core Fluid Cladding Lens in a Microfluidic Channel" by Tang et al., Lab Chip, 2008, vol. 8, p. 395, and in WIPO publication WO2008/063442, each of which is incorporated herein by reference in its entirety. These applications of fluid lenses are directed towards photonics, digital phone and camera technology and microelectronics. [0004] Fluid lenses have also been proposed for ophthalmic applications (see, e.g., U.S. Patent No. 7,085,065, which is incorporated herein by reference in its entirety). In all cases, the advantages of fluid lenses, such as a wide dynamic range, ability to provide adaptive correction, robustness, and low cost have to be balanced against limitations in aperture size, possibility of leakage, and consistency in performance. The '065 patent, for example, has disclosed several improvements and embodiments directed towards effective containment of the fluid in the fluid lens to be used in ophthalmic applications, although not limited to them (see, e.g., U.S. Patent No. 6,618,208, which is incorporated by reference in its entirety). Power adjustment in fluid lenses has been effected by injecting additional fluid into a lens cavity, by electrowetting, application of ultrasonic impulse, and by utilizing swelling forces in a cross-linked polymer upon introduction of a swelling agent such as water. BRIEF SUMMARY [0005] In an embodiment, an actuator for a fluid-filled lens comprises: a housing; a reservoir disposed within the housing; 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. [0006] In another embodiment, an actuator for a fluid-filled lens comprises: a housing having a first end and a second end; a reservoir disposed within the housing; and a slider slidingly disposed within the housing and disposed adjacent to the reservoir, wherein the slider includes a first end having a wedge shape configured to compress the reservoir, and wherein sliding of the slider from the second end of the housing to the first end of the housing causes the first end of the slider to compress the reservoir.
