Abstract: One of both eyes (e.g., a right eye) is made to view a reference blurred image (Cp), the other of both eyes (e.g., a left eye) is made to view blurred images (Cp+1, Cp+2, . . . ), and information on sensitivity to a difference in blur amount between the blurred images (Cp+1, Cp+2, . . . ) that the other eye was made to view and the reference blurred image (Cp) that the one eye was made to view is acquired. Additionally, the other eye is made to view the reference blurred image (Cp), the one eye is made to view the blurred images (Cp+1, Cp+2, . . . ), and information on sensitivity to a difference in blur amount between the blurred images (Cp+1, Cp+2, . . . ) that the one eye was made to view and the reference blurred image (Cp) that the other eye was made to view is acquired.

Abstract: A method for designing a spectacle lens includes: presenting a plurality of blurred images created by applying different degrees of blur to an original image and having a wearer see the blurred images; acquiring information on a sensitivity to blur of the wearer; and designing a spectacle lens based on the information on the sensitivity to blur of the wearer.

Abstract: An eyeglass lens design device designs a pair of aspherical lenses which have different strengths for the left and right lenses, and have rotational symmetry or axial symmetry around a component of a fixed focal length lens for a distance prescription comprising a fixed focal length lens or a progressive refractive lens, and includes an acquisition unit configured to acquire left prism amount information corresponding to a left-eye strength and right prism amount information corresponding to a right-eye strength, a calculation unit configured to calculate a computed value of a left prism amount and a right prism amount on the basis of the left prism amount information and the right prism amount information, and a change unit configured to calculate a design parameter change amount of the right-eye aspherical lens and/or the left-eye aspherical lens on the basis of the computed value of the left prism amount and the right prism amount, and to change a design parameter thereof on the basis of the calculated design parameter change amount.

Abstract: A sensitivity evaluation method includes: causing a wearer to view a target through a lens or a lens group capable of controlling at least one optical property among a spherical power, a cylindrical power, and an astigmatic axis angle; and acquiring information about a sensitivity of the wearer with respect to an aberration.
