ABSTRACT:
An attachment (10) for safety eyeglasses includes a mount (30) that mounts on an eyeglass temple bar, an earplug (32) that can fit into the ear canal to block noise, and a coupling (34) that connects the mount to the earplug. The mount includes a tube of elastomeric material that can be stretched over the temple bar to fix its position and prevent "jiggling". The coupling includes a wire of resilient plastic that is wound into a tight helix. The diameter of the helix is about 1 cm, which allows it to be stored between the rear of the outer ear and the skull, to minimize earplug motion when the earplug is not inserted into the ear canal.
