The Soflens Multi-Focal lens utilizes an aspheric center-near design. Because presbyopic needs vary widely, the Soflens Multi-Focal lens is available in two different ADD powers: a low ADD design (progressive up to +1.5D) and a high ADD design (progressive up to +2.5D). The high add design is distinctly different from the low add design in that, while it also affects a gradual power increase from periphery to center, there is a distinct central zone, or plateau, which boosts the near ADD power.
