Multiple near distances at arm’s length Increasingly, people are spending time indoors and exercising their vision mostly in short and intermediate distances. Gen X is craving for seamless acuity in various everyday tasks, at multiple near distances. They want to send a text while catching up their favorite TV show on a tablet, they are checking breaking news alerts on their mobile while working on their desktop. From 2D to 3D, Varilux X Series is setting a new reference criteria – vision volume Historically, progressive lens designers were considering a single target object for one gaze direction, the near vision zone in a progressive lens was set at 40 cm at 36 degrees. Today, Essilor designers have focused their efforts on vision at arm’s length, formulating new reference criteria: vision volume. This pioneer approach addresses the main limit of progressive lenses:the necessity to adjust head position to see sharp. No need to move the head to see sharp at near distances Essilor research has analysed in-depth the usual zone of vision in one posture. The objective was to meet most visual needs inside this zone.
