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.

The present invention relates generally to an ophthalmic device capable of monitoring neural frequencies and correlating the measured frequencies them to specific brain activity/functions. In some embodiments, profiles specific to the user of the ophthalmic device can be pre-programmed to tailor a brain activity/function profiles according to a user. Based on the determined brain activity/function from the correlation, a signal may be generated to provide feedback to the user. The signal may be transmitted to the user in one or more form. For example, the signal may be outputted to a wireless device in wireless communication with the ophthalmic device, and/or through an audible signal projected by an acoustic element, and/or a visual signal projected using a photon emitter, both which may be included in the ophthalmic device.
