Abstract: Provided is technology that makes it possible to design a progressive power lens appropriate for visual behavior of a subject. A method for designing a progressive power lens includes: a step (a) of determining a relationship between a line-of-sight passage position on a surface of a progressive power lens through which a line of sight of a subject wearing the progressive power lens passes and a reactive accommodation amount that the subject exhibits when the line of sight passes through the line-of-sight passage position, based on visual behavior of the subject; a step (b) of judging whether or not the reactive accommodation amount is within an appropriate range; a step (c) of determining a correction method for correcting the progressive power lens based on a result of judgement made in the step (b); and a step (d) of correcting a design of the progressive power lens based on the correction method determined in the step (c).

Abstract: A method for producing a polarizing lens having a high luminous transmittance and degree of polarization with astigmatism kept low, and a polarizing film and a polarizing lens. The method for producing a polarizing lens includes: contracting a polarizing film at a maximum rate of contraction of 5% or more and 30% or less under moist conditions; processing the polarizing film into a curve; drying the polarizing film at temperature T1; providing a mold having a cavity in which the polarizing film is placed in the inside; injecting a curable composition into the cavity; curing the curable composition to obtain a polarizing lens in which the polarizing film is placed in the inside; and annealing the polarizing lens at temperature T2, wherein a relationship between the temperature T1 and the temperature T2 satisfies the following expression (1): T1>T2 . . . (1).

Abstract: A progressive addition lens design method includes adjusting a lens surface shape to bring a difference between a first state when an object at a first location in a wearer's front and on the wearer's medial plane is visually recognized and a second state when an object at a second location positioned on the first location side in the horizontal direction at a constant height in the vertical direction is visually recognized in a plane parallel to a frontal plane and includes the first location at the time the lens is worn closer to a difference between a third state when an object at the first location is visually recognized and a fourth state when an object at the second location is visually recognized at the time a reference single focal lens corresponding to the progressive addition lens is worn or at the time equivalent to a naked eye.
