This lens design is Cosmetically the best looking lens of all the bifocals, showing virtually no sign of a segment. However, there is a 1 to 2mm blending range between the segment power and the lens prescription. This blending range has a distorted perspective that can prove to be non-adaptable for some patients. However, it is also a lens used with patients that are non-adaptive to progressive lenses.
