A shaft alignment apparatus sets a shaft alignment position (45), which is a mounting position with respect to an eyeglass lens (LE), of a lens holding shaft that holds the eyeglass lens (LE) interposed therein during the processing of the eyeglass lens (LE). A controller of the shaft alignment apparatus sets a shaft alignment position (45), other than at a geometric center (GC)of a target lens shape (60) to be processed, at which a processing inappropriate region (50) in the vicinity of the shaft alignment position (45) and the position of a hole (43) to be formed do not overlap each other, in at least a portion of cases where the shaft alignment position (45) is set with respect to the eyeglass lens (LE) having a hole formed through a lens surface thereof.


An ophthalmic analysis device for analyzing OCT motion contrast data including blood vessel information of a subject eye acquired by an ophthalmic OCT, includes: an analysis processing means configured to analyze the OCT motion contrast data to acquire a measurement result related to a capillary area of the subject eye, wherein the analysis processing means executes an alleviating process for alleviating the influence of great blood vessels having blood vessel diameters larger than those of capillaries on the measurement result to acquire the measurement result related to the capillary area.
