Abstract
Embodiments disclosed herein are directed to switchable lens devices, systems, and methods that include determining relative tilt and/or vergence rotation of a subject's eyes and focusing one or more lenses based on the determined vergence rotation or a change therein. The switchable lens device can include one or more sensors configured to detect movement of at least one eye of the subject (e.g., to determine a least one of position, velocity, or acceleration of at least one eye of the subject). For example, the switchable lens device can include one or more acceleration sensors that can be operably coupled to or associated with a first eye or a second eye of the subject.
