Claim Text:
1. A hinge for a fluid-filled lens assembly, the hinge comprising: a base having a first end for connecting to a temple arm of the lens assembly and a second end for connecting to a frame of the lens assembly, wherein the base includes a gap that is shaped to allow a tube for passing fluid to pass from the first end to the second end of the base, wherein the gap has a size that allows the tube to bend without kinking when the temple arm is rotated between an open position in which the temple arm is substantially perpendicular to the frame and a closed position in which the temple arm is substantially parallel to the frame, wherein the tube has an outer diameter measuring less than 2.0 mm and a wall thickness measuring less than 0.5 mm, wherein the base includes a peaked surface capable of engaging a rounded surface of the temple arm when the temple arm is rotated a first predetermined distance to create spring energy in the hinge that resists further rotation of the temple arm, and wherein the peaked surface is capable of releasing the spring energy in the hinge to accelerate the temple arm when the temple arm is rotated a second predetermined distance beyond the first predetermined distance.
