    Abstract: The visual perception of a lens wearer is not only along the gaze direction, but also has a non-zero transverse extension, which is called perceptual span. Perceptual span is skewed to extend further in the reading direction, i.e., the line portion to be read next relative to the line portion that was just read. A technique is provided that determines a pair of progressive ophthalmic lenses that take such perceptual span into account.

    Abstract translation: 透镜佩戴者的视觉感觉不仅沿着注视方向,而且还具有非零横向延伸,称为感知范围。 感知跨度倾斜以在阅读方向上进一步延伸,即接下来要被读取的线部分相对于刚读取的线部分。 提供了一种技术,其确定了考虑到这种感知跨度的一对渐进式眼科镜片。
