A method for manufacturing an optical member, and a related technique, the method including: applying desired laser processing to an anti-reflection film formed to coat an optical surface of an optical base material and having a multilayer structure including laminated layers of a low refractive index layer and a high refractive index layer, by irradiating the anti-reflection film with ultrashort pulse laser; and partially removing a predetermined layer including an outermost layer of the multilayer structure, the ultrashort pulse laser having a pulse width of 10 femtoseconds or more and less than 100 picoseconds, the anti-reflection film including a reactive layer that is relatively more reactive to irradiation with the ultrashort pulse laser than other layers included in the multilayer structure, wherein the reactive layer is subjected to the laser processing so as to be visually recognizable by visible light by being at least partially removed.
These spectacles have spectacle lenses that exhibit a myopia progression mitigating effect or a hyperopia progression mitigating effect. The spectacle lenses each have: a central clear region which achieves a prescribed refractive power for a wearer and includes an eye point of the spectacle lens; an annular functional region which has a portion having a different refractive power than the prescribed refractive power and surrounds the central clear region; and an annular peripheral clear region which achieves the prescribed refractive power and surrounds the functional region, wherein on the vertical straight line passing through the eye point, the width of the peripheral clear region in the vertical direction is smaller than the circle equivalent diameter of the central clear region.
An electronic dimming lens acquired by combining an electronic element for dimming and a lens, the electronic dimming lens including: holes that open on an outer face of the electronic dimming lens and are connected to electrodes for a positive electrode and a negative electrode in the electronic element; and terminal members that are molded to match a shape of the holes and are inserted into the holes, in which the terminal member is electrically connected to the electrodes inside of the hole and has one end part exposed to an opening of the hole. In accordance with this, reliability, durability, and producibility of terminals connected to electrodes of the electronic element for dimming can be configured to be superior.
