Abstract: The present invention provides a progressive-power lens affording superior wear comfort, even where a shallow base curve is employed in order to make the lens lighter and thinner, which is desirable in the terms of weight and aesthetic design. In the case of a progressive-power lens for correcting hyperopia whose distance portion has a positive refractive power, such lens is designed by giving preference to minimizing transmission astigmatism at each point on the principal sight line of the distance portion, but not giving preference to making the astigmatism of the lens surface zero at each point on the principal sight line. On the other hand, in the case of a myopia corrective progressive-power lens for correcting myopia whose distance portion has a negative refractive power, such lens is designed by giving preference to minimizing transmission average refractive power error at each point on the principal sight line of the distance portion, but not to making the astigmatism of lens surface zero at each point on the principal sight line.

Abstract: An object is to reduce the inconvenience given to the binocular vision function when wearing and using spectacles making use of a pair of progressive power lenses having different distance dioptric power for right and left. For this reason, the present invention associates, in a pair of progressive power lenses corresponding to the right and left eyes, an average dioptric power distribution and an astigmatism distribution determined from prescribed dioptric power and a wear state of one of the progressive power lenses with an average dioptric power distribution and an astigmatism distribution determined from prescribed dioptric power and a wear state of the other progressive power lens, and thereby average dioptric power distributions and astigmatism distributions of the respective progressive power lenses are changed.6

Abstract: A progressive power multifocal lens by which a substantially good "broad field of view" can be obtained for an eyeglass wearer without increasing time and cost required to produce the prescribed surface thereof. This progressive power multifocal lens belongs to a group of progressive power multifocal lenses designed under a certain rule in such a manner that fundamental elements such as a far vision power measuring position F and a near vision power measuring position N thereof meet a common wearing object. Further, in the case of this lens, a surface refractive power (in units of diopters) at the far vision power measuring position F is employed as a base curve (Bi). Moreover, a difference in surface refractive power between the far vision power measuring position F and the near vision power measuring position N is employed as an addition Di (in units of diopters). Furthermore, let W(Di, Bi) denote a width of a region in which values of a surface average additional refractive power along a horizontal section line extending below the near vision power measuring position N are not less than Di/2. In such a case, when arbitrary two progressive power multifocal lenses, whose additions are Da and base curves are B1 and B2, respectively, are extracted or selected from the group of the progressive power multifocal lenses, the following relation holds for B1>B2: W(Da, B1)>W(Da, B2).

Abstract: A progressive power omnifocal lens (1, 5) for constituting spectacles having for vision and near vision focuses, having an area in which the refacting power progressively changes (successively increases) from upper to lower positions in the vicinity of the horizontal center of the lens; and a main fixation line (4, 6) generally called an "umbilical meridian" formed in the progressive-change area, in which the degree of astigmatism along the main fixation line is substantially zero, and the main fixation line is gradually displaced toward the nose in accordance with the convergence of the eyes as it extends from an upper position to a lower position. The disposition of the main fixation line displaced toward the nose is varied depending upon the addition of the lens in such a manner that it is shifted upward as the addition of the lens is reduced, thereby optimizing the performance of the lens for a particular user.

Abstract: A progressive multi-focal lens is provided of the type having a distant viewing zone, a near viewing zone, and a progressive zone therebetween. The surface refractive power increases vertically from an upper portion of the lens to a lower portion as the line of sight scans from a distant view to a near view. Side zones are provided beside the progressive and near viewing zones. The side zones are spheric surfaces, with a dioptric refractive power in accordance with one embodiment being the arithmetic mean value of the refractive power of the near and distant viewing zones. This eliminates astigmatism problems in the side areas and permits normal side sight.

Abstract: To provide a bi-aspherical type progressive-power lens which provides an excellent visual acuity correction for prescription values and a wide effective visual field with less distortion in wearing, by reducing a magnification difference of an image between a distance portion and a near portion of a lens, and a method of designing the same. A progressive action of a progressive-power lens is divided in the vertical direction and the horizontal direction of the lens and then an optimal sharing ratio between the front and rear two surfaces of the object side and the eyeball side is set in each direction to configure one bi-aspherical type progressive-power lens, a sharing ratio of a progressive action in the horizontal direction of a rear surface (eyeball side surface) is set higher so that an advantage of increasing the visual field in the horizontal direction can be obtained, a sharing ratio of a progressive action in the vertical direction of a front surface (object side surface) is set higher so that a disadvantage of increasing an eyeball turning angle between the distance and near portions in the vertical direction can be restrained, also a wide effective visual field with less distortion in wearing can be provided by reducing a magnification difference of an image between the distance portion and the near portion on the progressive-power lens, further making it possible to obtain a bi-aspherical type progressive-power lens capable of reducing a machining time and cost by making it possible to machine only the surface of an eyeball side as a bilaterally asymmetrical curved surface coping with a convergence action of an eye in near vision after receiving an order, by using “bilaterally symmetrical semi-finished product” as an object side surface of the progressive refractive power lens.
