Abstract: The present invention relates to a variable focus lens. The variable focus lens comprises a fluid chamber having a protrusion formed along one opened end thereof. The fluid chamber is cylindrically shaped to house first and second non-miscible fluids therein, and the first and second fluids have different refractive indices. A transparent element hermetically is coupled with the opened end of the chamber with a predetermined gap from the protrusion of the chamber. A first electrode is disposed inside the chamber to act on the first fluid, and a second electrode is insulated from the first electrode. The variable focus lens can be easily fabricated to prevent bubble formation with the protrusion formed at the opened end of the chamber.
