摘要：
A bifocal spectacle lens and a method for creating a numerical representation of a bifocal spectacle lens are disclosed. The bifocal spectacle lens includes a distance portion, a near portion, and a transition section situated between the distance portion and the near portion. The distance portion is optimized in view of an optical power for distance vision and the near portion is optimized in view of an optical power for near vision. The transition section is determined such that the transition section creates a continuous transition between the distance portion and the near portion. The distance portion and the near portion are optimized independently of one another and put together with the transition section to form the numerical representation of the bifocal spectacle lens.
