Pushing the limits of geometry in lens personalisation.

Digital Ray-Path 2 pushes the limits of geometry in lens personalisation by incorporating the wearer’s accommodative capacity in the final lens calculation to further minimise oblique aberrations. This technology incorporates this factor into each individual lens and considers the accommodative object space, the volume defined by the points within the clear visual range, for each gaze direction.

Digital Ray-Path 2 works in synergy with nature. It utilises the innate power of the human eye to refine the optimisation process for personalised lenses

Lenses with Digital Ray-Path® 2 give eyecare professionals the ability to offer their patients the latest in lens personalisation technology. A unique technology to help them differentiate their businesses.


  • 11% of gaze directions are now optimised in traditional lenses.
  • 43% of gaze directions are now optimised in personalised lenses.
  • 99.5% of gaze directions are now optimised in lenses with IOT Digital Ray-Path 2.
