Progressive Lenses (Vari-focal lens) Progressive lens design or multi vari- focal design are the latest in the management of presbyopia (reading difficulty after the age of 40). This design avoids the line or curve that is evident in bi-focal lenses. Functionally, these designs are suited for daily wear as they do not obstruct the wearer from walking down stairs, riding a bike. Progressive design is especially suited for computer use.
