    • A novel plano lens and eyewear incorporating such lens is presented wherein the piano lens comprises a front surface curvature which is created by rotating an aspheric shape about an axis which is offset from an axis of the aspheric shape. In a preferred embodiment, the aspheric shape is an ellipse or at least is an aspheric shape, a segment of which has an elliptical arc. This elliptical arc is rotated about an axis spaced (offset) some distance from a major or minor axis of the ellipse. In a more preferred embodiment, the ellipse is rotated about an axis spaced from and parallel to the major or minor axis of the ellipse, but in the same plane as the ellipse. The resulting surface of this preferred lens configuration will have a cross-section in a first axis which is a segment of an ellipse, and a cross-section in a second axis (perpendicular to the first axis) which is a segment of a circle. A significant feature of the preferred front lens configuration is that the surface generated is rotationally symmetric.
    • 提出了一种新颖的平面透镜和包含这种透镜的眼镜,其中,钢琴镜片包括通过围绕非球面形状的轴偏移的轴旋转非球面形状而产生的前表面曲率。 在优选实施例中,非球面形状是椭圆形,或者至少是非球面形状,其一部分具有椭圆弧。 该椭圆弧围绕与椭圆的主轴或短轴间隔(偏移)一定距离的轴旋转。 在更优选的实施例中,椭圆围绕与椭圆的主轴或短轴平行但与椭圆相同的平面旋转。 该优选透镜构造的所得表面将在第一轴线上具有椭圆形截面的横截面,以及作为圆形部分的第二轴线(垂直于第一轴线)的横截面。 优选的前透镜配置的显着特征在于所生成的表面是旋转对称的。
