IOT Digital Ray-Path 2

IOT Digital Ray-Path 2 is IOT’s foundational technology for minimizing oblique aberrations in personalized and compensated free-form lenses.



In addition to mathematically compensating for oblique aberrations, IOT Digital Ray-Path 2 adds the intelligent use of the wearer’s accommodation: the small power adjustments the eyes naturally make to view objects at different distances.

Pushing the limits of geometry in lens personalization

IOT Digital Ray-Path 2 pushes the limits of geometry in lens personalization by incorporating the wearer’s accommodative capacity in the final lens calculation to further minimize oblique aberrations.

Oblique aberrations, found in any lens, include astigmatic and spherical power errors. These errors create an out-of-focus image as the wearer’s gaze moves away from the optical center of the lens. Eliminating them completely is not mathematically possible. Some residual power error remains, causing a slight blur.

Here’s how it works

IOT Digital Ray-Path 2 calculates a unique back surface design for each lens with a three-step optimization process.
