    Abstract: Provided is an eyeglass lens configured to cause rays that have entered from an object-side surface to be emitted from an eyeball-side surface and cause the emitted rays to converge at a predetermined position A. The eyeglass lens includes a lens base material having a plurality of base material convex portions on at least one of the object-side surface and the eyeball-side surface, and the eyeglass lens has a configuration for suppressing stray light rays that do not pass through the vicinity of the predetermined position A or the vicinity of the position B that is closer to the object than the predetermined position A is.

    Abstract: A technique capable of easily and highly accurately perform positioning of a lens member having a convex optical surface. A lens positioning mechanism is configured to include: a member holding unit that has a function of holding a lens member via an auxiliary tool attached to a second surface of the lens member having a first surface, which is a convex optical surface, and the second surface, which is an optical surface facing the first surface, and biasing the held lens member toward a side of the first surface; and an attitude control unit that abuts on a predetermined portion on the first surface of the lens member biased on the member holding unit to regulate a position of the predetermined portion and positions the lens member in a predetermined attitude.

    Abstract: A semifinished lens is configured with at least three marks for specifying the center position of a frame shape. When the semifinished lens is viewed in an optical axis direction, the at least three marks include a pair of marks located on a first straight line passing through the center position and a mark located on a second straight line that is orthogonal to the first straight line and passes through the center position.

    Abstract: An optical article, such as a spectacle lens, includes, on a substrate, a photochromic layer containing a photochromic dye and a resin component, and a protective layer. The indentation hardness of the photochromic layer in the thickness direction is in a range from 0.1 to 10 mgf/μm2. The value defined by the indentation hardness of the protective layer in the thickness direction multiplied by the thickness of the protective layer is five or more times and nine thousand or less times the value defined by the indentation hardness of the photochromic layer in the thickness direction multiplied by the thickness of the photochromic layer.
