Techniques for providing eyewear with electrical components are disclosed. The electrical components can provide electrical technology to eyewear (e.g., eyeglasses) without having to substantially compromise aesthetic design principles of the eyewear. Often, the electrical components can be attached to the eyewear as an after-market enhancement. The electrical components can operate independently or together with other electrical components provided elsewhere. In some embodiments, tethered electrical components can be coupled to electrical components in or attached to a pair of eyeglasses. Tethered electrical components, alone or in combination with eyeglass electrical components can be used for a variety of different applications and uses.
