Behind the wheel, more than 90% of decisions and reactions depend on good vision. Glare delays driver reaction times. Xperio lenses virtually eliminate blinding glare and offer a better anticipation on the road. 

In 2008, a specialized institute measured driver reaction times for Xperio polarized lenses vs ordinary sunlenses⁽²⁾.
Driver reaction time is improved by 1/3 of a second, allowing drivers to stop the vehicle 7 meters sooner at 80km/h.
It’s the length of an intersection! 

In the presence of glare, it has been proven by usage tests⁽¹⁾ that polarized lenses improve contrast sensitivity by 75% allowing wearers to enjoy a better clarity of vision  as opposed to ordinary sunlenses.

In addition, Xperio polarized lenses passed the standard test of traffic light recognition(3) (Z 80.3)

Xperio lenses are recommended to drive more safely !
