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.
