    • A manufacturing method of a progressive multi-focal lens which has a progressive surface area comprising a distance portion and a near portion, which have different refractive powers, and a progressive portion positioned between them in which the refractive power changes progressively. The progressive surface which reflects customized information for each individual user including at least one of the information concerning each individual user's eyes or lifestyle of the user is designed. A lens design process provides processing data for the progressive multi-focal lenses with the custom-made progressive surfaces. By so doing, it is possible to provide the most appropriate spectacle lenses for the users and, at the same time, it is possible to eliminate the process of storing lenses in a semi-finished state after being processed so that it is possible to provide lenses which are suited to users at a lower cost.

    • In a multifocal lens for eyeglass provided with visual field areas having different refractive powers, being a distance-vision area and a near-vision area, a multifocal lens for eyeglass (10) is provided, in which the difference of the average surface power D11 of the distance-vision area (11) of the surface (2) on the side of the object and the average surface power D12 of the near-vision area (12) is made mathematically less than the addition power Add. Furthermore, a specific addition power Add is provided by adjusting the average surface power D21 of the distance-vision area of the surface (3) on the side of the eye and the average surface power D22 of the near-vision area. It becomes possible to adjust the average surface powers D11 and D12 of the surface (2) on the side of the object such that the difference of magnification of the distance-vision area and the near-vision area becomes little. Furthermore, it is also possible to make the difference of the average surface powers D11 and D12 of the surface (2) on the side of the object little. Consequently, a multifocal lens can be provided, whereby a comfortable visual field can be obtained, in which there is little jumping and warping of images due to the difference of magnification, and furthermore, the clear-vision area having improved astigmatic aberration is wide, and there is little jumping of images, and the like.

    • A variable focus type eyesight correcting apparatus in which a plurality of optical lenses are superimposed on each other and in which a refracting power is changed by relatively sliding the lenses in the direction of the superimposed surfaces, achieves a reduction of astigmatism, assurance of uniform refracting power, prevention of diffused reflection, which could be caused if a plurality of refractive surfaces are present, and miniaturization of lens system. When a change of astigmatism in each constituent lens in the variable focus type eyesight correcting apparatus is expressed by contours spaced at intervals of arbitrary diopter, the contours are arranged to be substantially linear and parallel to the principal meridian. The astigmatism becomes absent and the refracting power becomes constant in the region where the eyeglass lenses of the present invention are superimposed on each other, whereby the lenses of the invention can have the optical performance identical to that of single focal lens.

    • A progressive power lens provides a large clear vision area from a far-distance use section to a progressive section, wherein an astigmatism imbalance during vision through both eyes is eliminated, and eye movement between far and near distance use takes place smoothly. Astigmatism is distributed asymmetrically in the progressive region of the progressive power lens with respect to a meridian in such manner that a larger astigmatism occurs in a nose-side region than in an ear-side region. By so doing, distribution of astigmatism in the nose-side progressive region is eased to match that of the ear-side progressive region. Moreover, by making the increasing ratio .beta. of the astigmatism in the far-near direction milder than the increasing ratio .alpha. of the astigmatism in the left-right direction, a large clear vision area is obtained and the astigmatism imbalance during vision with both eyes is eliminated. Moreover, eye movement between the far-distance use and near-distance use takes place smoothly.

    • A progressive multifocal lens used for correction of vision includes a progressive refractive surface positioned closest to the user's eye when the lens is worn by the user, and a second surface on an object side of the lens. Because the base curve of the second surface can be a constant spherical surface, it is possible to prevent variations in magnification due to shape factors. In addition, differences in magnification between a distance-vision region and a near-vision region of the progressive multifocal lens are reduced, and variations in the magnification of a progressive refractive region in the progressive multifocal lens can be suppressed. Accordingly, image jumping and warping due to differences in magnification are reduced, resulting in a comfortable visual field for the user. A progressive multifocal lens for correction of astigmatism includes a progressive refractive surface and a toric surface that are combined to form a composite surface positioned closest to the user's eye when the lens is worn by the user.

    • An additional aspherical surface amount is defined by a sum of the optimum amount at a distance portion and the optimum amount at a near portion on a progressive refractive surface. Assuming that the ratio is taken as &agr;:&bgr;, the additional aspherical surface amount is added to the progressive refractive surface in such a manner that &agr; and &bgr; satisfy a relationship of &agr;+&bgr;=1. With this configuration, in the case where an aspherical shape is added to a progressive power lens for correcting visual acuity for the purpose of improving the optical performance and thinning the lens, the optimum aspherical shape can be given not only to a region along a main meridian line but also to the whole of the progressive refractive surface.

    • To provide an optical element, an optical lowpass filter, and a solid-state imaging device of which quality and capability are hard to deteriorate even if they are continually subject to both of a high-temperature, high-humid environment and a normal environment. An optical lowpass filter includes a first birefringent plate, an IR-cut glass, a ¼ retardation film, a second birefringent plate, and a pressure sensitive adhesive as a bonding layer bonding these members. The pressure sensitive adhesive primarily contains a pressure sensitive adhesive main agent polymer composed of a monomer including many hydrophilic groups so as to enhance permeableness of water within the pressure sensitive adhesive. In addition, by selecting a mixing weight ratio of the pressure sensitive adhesive main agent polymer, the permeableness can be further enhanced. Therefore, such an optical element and an optical component can be obtained that are hard to become white turbid under the high-humidity environment by making the pressure sensitive adhesive thereof have efficient and saturated water; and that discharge water that is inside the pressure sensitive adhesive from the periphery thereof to the air so as to recover their optical properties in a short period of time under the normal environment.
