Abstract
Disclosed are powered or electronic ophthalmic devices or lenses which can have the ability to monitor and sense extreme gaze angle. Also disclosed is the use of extreme gaze angles to control the focal state of the lens as well as for augmenting, control of, or input to, other device parameters of the powered or electronic ophthalmic lens. Applicants have researched and determined what are believed to be acceptable ranges of both upward and downward extreme gaze angles which are not only measurably distinguishable from normally occurring gaze angles associated with everyday activities, but which are still achievable by the wearer if purposeful, as they are still within human eye movement capability.
