Goodrich Optical Digital Ray-Path 2

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

In addition to mathematically compensating for oblique aberrations, Goodrich Optical 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.

Goodrich Optical 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.

The relationship between eye accommodation, the accommodative object space, and compensated power has long been understood. Until now, lens calculation technology has not been sophisticated enough to create free-form digital lenses that take full advantage of this knowledge.

Accommodation is the wearer’s natural ability to focus on different distances, without moving their eyes or head, by stimulating or relaxing the lens within the eye. Goodrich Optical Digital Ray-Path 2 incorporates this factor into each individual lens calculation. Goodrich Optical Digital Ray-Path 2 also considers the accommodative object space, the volume defined by the points within the clear visual range, for each direction of gaze.

Goodrich Optical Digital Ray-Path 2 mathematical methods take advantage of the natural ability of the visual system to compensate for a portion of the spherical component of oblique aberration.

Goodrich Optical Digital Ray-Path 2 considers small power adjustments wearers can naturally make at each fixation point. Oblique aberrations are minimized, in a more effective way, offering wearers impeccable visual quality.
