PROBLEM TO BE SOLVED: To improve searchability in inadvertent missing in the dark by building a sensor for detecting wearing/non-wearing of spectacles and energization control circuits for intermittently energizing light emitting elements to emit light, when the sensors detect non-wearing of spectacles. SOLUTION: These spectacles are composed of lenses and a frame. This frame is composed of lens frames, nose pads, hinges, temples, ear bend parts 25, etc. The circuit modules 3 formed by integrating sensors 4, light emitting elements 5, batteries 6, and the energization control circuits 7 into a single unit are built into the front end side of the bend parts 25. The energization control circuits 7 of such constitution are operated by the on output when the sensors 3 detect the non-wearing state of the spectacles, by which the light emission drive current is supplied intermittently from the batteries 6 to the light emitting elements 5. As a result, the front ends of the ear bend parts 25 intermittently light only during the non-wearing state of removing the spectacles. Then, even when a person having weak sight removes the spectacles and forgets the place for placement, the person can easily find out the location of the spectacles. |
