1. Optical projection time-piece attachment for spectacles or sunglasses comprising:
- (a) a miniature housing with mounting and securing means for attachment to a pair of spectacles or sunglasses frame such that the normal field of vision is not obstructed,(b) micro electronic circuitry means to generate electrical time of day functions,(c) electric light emitting display panel means to display time of day using said electrical time of day functions,(d) lens means to project an image of said display, said display panel and said lens disposed in said housing such that said display image is generally projected outward approximately at an angle of 45 degrees in a direction relative to a diametrical line of one viewing surface of the spectacles or sunglasses,(e) a clear reflective window means to intercept and partially reflect said projected display image back towards the eye of the spectacles or sunglasses wearer so as to produce a virtual image of said time display superimposed on the normal field of view when said display is illuminated,(f) convenient means to adjust and focus said display image,(g) means for supplying electric power to said micro electronic circuitry and said electric light emitting display,(h) readily accessible press button switch means to activate said electric light emitting display when required,(i) further miniature switch means to set said electrical time of day functions.

Abstract
A miniature time-piece attachment for use on spectacles or made as an integral component of a spectacles frame. The time-piece is of the electronic type displaying the time value as miniature light emitting numerical display when a miniature button is pressed. The time display is projected optically by a lens and clear transparent window arrangement such that the time display appears as a virtual image superimposed and projected at infinity on a side of the normal field of view of the spectacles wearer. When the display is not illuminated the normal field of view of the spectacles wearer is not impaired, or impaired as little as possible.
