摘要：
The invention provides multi-focal segmented lenses with boundaries that include at least one blended portion and at least one sharp portion. The lenses may possess, for example, the aesthetic advantage of blended multi-segment or progressive lenses while largely retaining the functional advantage of multi-segment lenses with sharp segment boundaries.
