Introducing Xtend™ technology
Varilux X series introduces a new reference criterion: volume of vision. This volume of vision provides dynamic vision in a sphere at arm's length. This pioneering approach to near vision is a revolution in lens conception and is made possible by the new Xtend technology. This technology manages multiple targets for the same gaze direction and delivers the highest match with wearer's visual needs within arm's reach. Through Xtend technology, Varilux researchers have completely re-shaped a specific zone: the Arm's Length Vision zone (ALV).
