DuraTrack measures viewing behaviour in 3D to identify frequently used lens regions and incorporate eye/head movement data into personalised design.
Analysing actual eye and head behaviour through 3D measurement
From viewing behaviour to a lens-use map
Durabon's guide assigns the name DuraTrack to the Eye Shuttle process. This VR-based process records actual eye/head behaviour as input for personalised design.
Measurement process
Eye/head tracking sensors measure movement patterns in 3D. According to the catalogue description cited in the guide, a VR headset objectively measures actual eye movements and maps frequently used lens regions.
The measured data adapts lens-power distribution to the wearer's movement pattern. The headset measures viewing behaviour; the final product is a prescription spectacle lens.
Difference from near-corridor calculation
DuraFit Inset and Core Inset calculate horizontal near-path displacement. DuraTrack examines dynamic eye/head behaviour and frequently used lens regions. They have different inputs and roles in personalisation.
Featured example: ReadMax
The guide refers to ReadMax when explaining this process. Its catalogue addition range is 0.25–1.50 D. That is ReadMax product data, not an independent DuraTrack performance specification.
