ABSTRACT:
A sleep-preventing device incorporated within a pair of glasses having a light emitting diode, a photo diode, a buzzer, a power source and a printed circuit board. The printed circuit board is electrically connected to the light emitting diode, the photo diode, the buzzer. The photo diode is lodged in the bridge of the glasses and protrudes from a nosepiece of the glasses. An earpiece of the glasses has a cavity to receive the printed circuit board and the light emitting diode. An opening of the cavity is covered by a plate and a cover on which the printed circuit board is disposed. The plate has a number of holes to receive the light emitting diode, in which bores of the holes are oriented towards the photo diode so that the photo diode receives the light from the light emitting diode.
