摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： In a process of determining the surface shape of each of progressive multifocal lenses for use as lenses in eyeglasses, radii of curvature at main points are calculated, and then the surface is divided into a plurality of lattice sections, and then a curved-surface equation in the form of a bicubic expression is used for each section to determine the surface shape of the lens. A coefficient of each of the bicubic expressions is determined under a condition that continuation is established to curved-surface equations of sections adjacent at a boundary line between the sections to the derivatives of second order. Therefore, the surface shape of the lens obtained by the curved-surface equation for each section can be formed into a continuous and smooth surface. Since the curved surface can be determined for each section, a partial correction can easily be performed, if necessary. As a result, a progressive multifocal lens can be provided which exhibits smooth astigmatism curves and a large clear field of vision to meet a variety of specifications. Thus, lenses for eyeglasses each having a clear field of vision can be provided.

摘要： A progressive power lens is conventionally so designed that a distance portion and a near portion are linked together in a successive manner, and thus framing cannot be done in a manner as to fully achieve the best optical properties of the near portion. The present invention provides, on the other hand, a progressive power lens that is designed to make the near portion closer to an eyeball without impairing the optical properties of the progressive power lens. Accordingly, both the distance portion and the near portion can be framed with the ideal fitting, and the resulting eyeglasses can be less in distortion and fluctuation.

摘要： This semiconductor photodetector includes a photoabsorption layer, an n-type first semiconductor layer, and a p-type second semiconductor layer. The photoabsorption layer comprises an n-type first layer and a p-type second layer formed in contact with the first layer. The first semiconductor layer is arranged on the side of the first layer and has a shorter wavelength at a light absorption edge and a lower refractive index than in the photoabsorption layer. The second semiconductor layer is arranged on the side of the second layer and has a shorter wavelength at a light absorption edge and a lower refractive index than in the photoabsorption layer. When a predetermined reverse bias voltage is applied between the first and second semiconductor layers, the first layer is entirely depleted and the second layer is partially depleted.
