Abstract: The disclosure relates to a spectacle lens comprising: a lens base member; a multi-layered anti-reflection film placed on the lens base member, and including a layer mainly made of silicon dioxide as an outermost layer; and a water-and-oil repellent layer provided in contact with the outermost layer of the multi-layered anti-reflection film, and made by using, as raw materials: at least one kind of a first fluorine-substituted alkyl group-containing organosilicon compound and a second fluorine-substituted alkyl group-containing organosilicon compound. The disclosure also relates to methods of producing a spectacle lens that is capable of retaining a sufficient water-and-oil repellency over an extended period, and having sufficient edge processability.

Abstract: A light emitting diode is composed of a generally T-shaped body section (36) and a resin forming section (37) projected on a front surface of the body section (36). The body section (36) has an upright portion (32) inserted into a hole (51) provided in a motherboard (50) and base portions (31a and 31b) which extend from the upright portion and which are mounted on a peripheral edge of the hole (51). The resin forming section (37) includes a non-translucent frame (40) extending from a front surface of the upright portion (32) and an extension part (41) further projecting forwardly larger than the frame. The extension part (41) has a mounted portion (42) mounted on the peripheral edge of the hole (51) of the motherboard (50). Mounted in the concave portion (44) provided in the frame (40) is a light emitting diode element (34), which is sealed by a sealing body (45) of a translucent resin.
