Abstract: Various embodiments disclose a quasi progressive lens including a first optical zone capable of providing distance vision, a second optical zone capable of providing near vision and a transition zone connecting the first and second optical zones. Physical dimensions (e.g., length and width) of the transition zone are adjusted to increase the size of the second optical zone in comparison to progressive lenses and to reduce residual cylinder power and aberrations along the convergence path in comparison to bifocal lenses.

Abstract: Described herein are systems, devices, and methods to manufacture a feature onto the rim of an ophthalmic lens. In one embodiment, there are multiple lens rim features, and they are substantially restricted to the periphery of the lens. In alternative embodiments, the lens rim features are substantially restricted to either the top half or the bottom half of the periphery. In some embodiments, the features are added to a lens that has been finished for vision correction, whereas in other embodiments the features are added to a semi-finished lens. In one embodiment, there is a device for printing lens rim features onto an ophthalmic lens, and in another embodiment there is a system for printing such lens rim features. One embodiment is a method for printing a lens rim feature onto a lens, including the use of a device with a print-head and one or two grasping devices.
