Abstract: An aspect of the present invention relates to a method of determining a manufacturing condition of a polythiourethane eyeglass lens obtained via a process of obtaining polythiourethane by polymerization reaction of an iso(thio)cyanate compound and a thiol compound, comprising determining a candidate composition for a starting material mixture and a candidate polymerization reaction condition employed in the polymerization reaction in actual manufacturing; polymerizing the starting material mixture of the candidate composition that has been determined under the candidate polymerization reaction condition to obtain a test sample; testing the obtained test sample by irradiation with a xenon lamp to determine whether or not change into red-like color is present following irradiation with the xenon lamp; and determining a starting material mixture composition and a polymerization reaction condition to be employed in the polymerization reaction in actual manufacturing with the use of a result of the determination as an indicator.

Abstract: A spectacle wearing parameter measurement device used in measurement of a spectacle wearing parameter of a subject who is to wear a spectacle frame, the spectacle wearing parameter measurement device includes: an information processing unit that acquires each of a first image as a face image of the subject in a spectacle-frame wearing state and a second image as a face image in a spectacle-frame non-wearing state and prepares a third image obtained by associating the first image and the second image; a display screen unit that displays the third image prepared by the information processing unit; an operation unit that specifies a measurement reference point of the spectacle wearing parameter on the third image displayed on the display screen unit; and a measurement computation section that calculates the spectacle wearing parameter by using data of the specified measurement reference point.
