The Diffrax bifocal lens allowed a segment of individuals with bifocal needs the option to wear contacts. Now, there are a variety of bifocal contact options.
Basically, the Diffrax bifocal lens works by providing near vision and distance vision to the wearer. The contact lens wearer is allowed clear and proper vision because the lens does all the work by bouncing light in whichever direction is needed in order to view the object.
