Various embodiments of an eyeglass and eyeglass system are provided that can maintain the geometric and optical quality of a lens supported by the eyeglass. The processor may be capable of detecting proximity of an encasement based upon the NFC device, and changing an operational mode of the interface device based upon detecting the proximity of the encasement. The microorganism belonging to the genus Escherichia sp. By placing a quarter wave plate between the n-channel variable optical attenuator array and the partially transparent reflective means in the dynamic channel equalizer chip, the device can be rendered polarization insensitive. The second electrode is disposed at a distance from the first electrode.
