    摘要: In the disclosed lens, one lens surface is divided into an upper distance-vision portion FT, a lower near-vision portion NT, and a varying or transitional region PB between the two other portions. In the upper distance-vision portion, the surface contains a far reference point B.sub.F and exhibits predetermined average distance-vision surface refractive powers D.sub.F. The lower near-vision portion contains a near-vision reference point B.sub.N and has predetermined average near-vision surface refractive powers D.sub.N. The transitional region exhibits average surface refractive powers D.sub.P which effect a smooth transition from the distance-vision portion to the near-vision portion. The surface is divided into a temporal portion and a nasal portion by a principal meridian M which forms an umbilical line.

    摘要: An ophthalmic lens in which one surface is provided with at least one region, in which the refracting power is practically constant except for aspherical corrections, and at least one transition region which is adjacent to the region having practically constant surface refracting power, and in which the surface refracting power increases or decreases continuously, and the other surface is provided with an astigmatic effect. The orientation of the surface having an astigmatic effect relative to the surface having continuous refracting power change is dependent on the position of the axis of the astigmatism of the eye. The surface having an astigmatic effect deviates from the toric shape and is independent of the orientation of the surface relative to the surface having continuous refracting power change which is a surface optimized for the axial position of 0.degree..

    摘要: A spectacle lens with a high positive refracting power, whose front surface has an aspheric, rotationally symmetric effective part. The effective part is configured in accordance with the following equation: ##EQU1## where z is the sagitta, h is the distance from the optical axis, C is determined by the desired refracting power of the front surface at the vertex, and K and I.sub.i are aspheric coefficients. The aspheric coefficients K and I.sub.i are determined so that either the visual acuity V is a maximum or .vertline..DELTA.R.vertline.+.vertline..DELTA.S.vertline. is a minimum. The lens produces a pattern of aberration which allows complete utilization of the visual field for dynamic vision.
