摘要： The invention relates to a method comprising the following steps:—a bridge width (b), a glass length (I), and a frame glass angle (fF) are predefined as eyeglass frame data;—a base curve (BK) as well as a nasal and a temporal facet position (aFn, aFt) are predefined as eyeglass lens data;—a user's pupil distance (pL, pR) is predefined as user data;—a horizontal angle of tilt (fG) of the eyeglass lens (12) is determined at a reference point in the used position, the reference point being the point of intersection between the horizontal main beam facing the eye in the neutral viewing direction (NBR) of the user and the area (14) of the eyeglass lens which faces the object, and the horizontal angle of tilt (fG) being the angle enclosed by a horizontal tangent (26) of the area (14) of the eyeglass lens (12) which faces the object at the reference point (B) and a straight horizontal reference line (HR) located on a plane that extends perpendicular to the horizontal main beam in the neutral viewing direction (NBR) of the user. Also disclosed are a device and a computer program product.

摘要翻译： 本发明涉及一种包括以下步骤的方法：将桥梁宽度（b），玻璃长度（I）和框架玻璃角度（fF）预定义为眼镜框架数据; - 基准曲线（BK）以及 作为鼻和时间刻面位置（aFn，aFt）被预先定义为眼镜透镜数据; - 用户的瞳孔距离（pL，pR）被预先定义为用户数据; - 眼镜透镜的水平倾斜角（fG） 12）在使用位置的参考点处被确定，参考点是在用户的中立观察方向（NBR）和眼镜镜片区域（14）之间的面向眼睛的水平主光束之间的交点 面对物体的水平角度（fG）是由参考点（B）处的面对物体的眼镜镜片（12）的区域（14）的水平切线（26）包围的角度，以及 位于垂直于水平主梁的平面上的直的水平参考线（HR） 中性观察方向（NBR）。 还公开了一种设备和计算机程序产品。
