A lens for eyewear is configured to reduce the appearance of scratches on the lens and/or increase the durability of the lens. The lens can include a functional stack bonded to a lens body. The functional stack can include a functional layer, such as a thin film coating, sandwiched between the lens body and an optical-grade transparent film. The functional stack can increase abrasion resistance and environmental durability of the lens, and can reduce the appearance of scratches on the lens. The combined lens body and functional stack can increase the durability of the lens relative to a lens with a thin film coating (e.g., a gradient or mirror stack) on an external surface of the lens.

An eyeglass lens piece (10) configured for both forward and rearward viewing by a user comprises at least one curved transparent section extending in front of, above, between and below the user's eyes and a distance laterally from the sides of said user's eyes to the approximate sides of the user's head, a housing (11) arranged at an edge in the lower section (12) of the lens piece (10), projecting from the lens piece, and a mirror (15) arranged in the housing in a position offset from the curved transparent section.

A rear-viewing mirror assembly for a pair of glasses having an arm, the mirror assembly includes a housing forming an inner area and configured to secure to the arm; a locking mechanism disposed within the inner area of the housing; an elongated rod extending partially outside the housing and engaged with the locking mechanism; and a mirror rigidly attached to the elongated rod.

An intraocular lens is configured to reduce or eliminate oblique incident light photic disturbances in the eye. The lens includes anterior and posterior surfaces defining a central lens optic extending from the anterior to the posterior surfaces and a peripheral portion outside of the central lens optic. The peripheral portion is a prismatic lens that redirects oblique incident light on the peripheral portion forward of the nasal retina in the eye and onto the ciliary body/pars plana region.

A system comprises a smartwatch and an eyeglass frame. The eyeglass frame comprises a front piece, a pair of temples, and an optical element connected to the front piece. Each temple is hinged to an end of the front piece to allow the pair of temples to move between a folded position and an open position, where at least one temple of the pair of temples comprises an adapter to receive the smartwatch. The optical element is connected to the front piece and is configured to reflect light from the smart watch to an eye of a user.

An ophthalmic lens design method includes: acquiring first information about a purpose of an ophthalmic lens; acquiring second information about at least one of a visual line of a wearer for the purpose, a place, a use tool, and a body of the wearer; acquiring data indicating a number of first regions, positions, shapes, and sizes of a plurality of first regions set on a surface of the ophthalmic lens, and distances to a target viewed through the first regions; setting a variable numerical value among numerical values indicating the number of first regions, the positions, the shapes, and the sizes of the plurality of first regions, and the distances in the data and setting the plurality of first regions and the distances on the surface; and setting a target aberration distribution based on the plurality of first regions and the distances that have been set.
