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.
