Abstract
The present invention provides a device for an energizable Ophthalmic Lens with an event coloration mechanism. The event coloration mechanism may color or change color based on some predefined event. For example, a predefined constituent or predefined condition of the tear fluid may be indicative of the predefined event, and the event coloration mechanisms may interact with the tear fluid, accordingly. The event coloration mechanism may provide the energizable functionality of the Ophthalmic Lens in some embodiments. In others, the event coloration mechanism may be passive but may interact and interface with the electrical components of the Ophthalmic Lens, such as, for example, those included within the Media Insert. Event coloration mechanisms may be combined with additional functionalities that may be included in an energizable Ophthalmic Lens.
