This hearing device, for example, includes a vibrator for transmitting vibration corresponding to a voice signal to the nasal bone of a user to let the user hear sound. The hearing device may further preferably include an eyeglass-type housing for carrying the vibrator in a position at which a nose pad is provided. The hearing device may also preferably incorporate a voice signal reception unit for receiving, wirelessly or by wire, a voice signal generated by an external sound source, or an internal sound source for self-generating a voice signal. When implementation as a hearing aid or a sound collector is contemplated, the external sound source or the internal sound source may preferably be a microphone for collecting ambient sound.

Aspects of the present invention relate to a head-worn computer having a see-through computer display, a frame mechanically adapted to hold the see-through computer, a first side arm pivotally attached to the frame and adapted to hold the head-worn computer in place on a head of the user, wherein the first side arm comprises a temple section and an ear horn section and the temple section further comprising a compartment adapted to contain a battery, wherein the battery powers the see-through computer display.

A smart head-mounted device includes a first sub-eyepiece, a second sub-eyepiece, and a nose bridge. The first sub-eyepiece includes a first eyepiece frame and a first temple, and the first eyepiece frame has a first connecting portion; the second sub-eyepiece includes a second eyepiece frame and a second temple, and the second eyepiece frame has a second connecting portion; the nose bridge has a third connecting portion and a fourth connecting portion; and the first eyepiece frame is detachably connected to the nose bridge via the first connecting portion and the third connecting portion, and the second eyepiece frame is detachably connected to the nose bridge via the second connecting portion and the fourth connecting portion.

An eyewear frame having at least one frame component including a stimuli-responsive polymer is provided. The at least one frame component has a physical property which is reversibly changeable in response to a stimulus of non-thermal origin applied to the stimuli-responsive polymer. An eyewear including the eyewear frame, and a method of adjusting the eyewear frame are also provided.
