摘要： A progressive optic has an optical preform wherein the radius of curvature of the surface is altered by forming discrete spherical portions across the surface. A thin intermediate layer, having a different refractive index from the optical preform, is then cast over the formed optical preform surface. The optical preform having the thin intermediate layer is then cast with a resin superstrate layer which restores the curve of the optic. Each spherical section, defined by the spherical portions and corresponding portions of the outer surface of the superstrate layer, alters the spherical power of the adjacent spherical section by about 0.03 D to 0.05 D.

摘要： A method for providing a contact lens for a patient. According to this method, an optical preform is selected, and a resting position of the optical preform on the patient's eye is determined. An optical feature is also located on a patient's eye. Then, a reference position is located on the surface of the optical preform coincident with the optical feature on the patients eye, when the optical preform is in the resting position. Finally, the optical modification is provided on the optical preform at a location based on the reference position on the optical preform, either by machining the preform itself or by machining a mold that is subsequently used to form the lens.

摘要： Disclosed are apparatuses and manufacturing methods for a fluid filled lens reservoir system. The eyeglass reservoir system includes a temple piece having a cavity, a bladder positioned within the cavity and configured to repeatedly compress and relax, the bladder being made of a flexible material, and a connecting tube coupled to an inlet port of a lens module and to the bladder, configured to carry a fluid between the bladder and a fluid filled lens cavity of the lens module. The eyeglass reservoir system further comprises a compression arm contacting the bladder and configured to transmit force from an actuator to the bladder to cause movement of the fluid between the bladder and the connecting tube. The bladder and connecting tube are made of a flexible material such as polyvinyledende difluoride. The connecting tube further comprises a flared end configured to couple to the inlet port of the lens module.
