  • Patent number: 10261339
    Abstract: Embodiments of a skin contact reduction device that is substantially spherically shaped and attaches to the temple portion of facial equipment that goes over the ear or alongside the wearer's face. The device is directionally positioned with a larger opening pointing towards the front of the wearer's face and a smaller opening towards the rear. Both the larger front opening and interior of the device are significantly larger than the width of the temple portion of the facial equipment and therefore the device does not compress or stiffen when installed. The smaller rear opening of the device resiliently grips the temple portion of the facial equipment. Once attached, the device is adjusted by the wearer to a preferred position to keep a wearer's equipment on their face while minimizing contact and pressure between the temple or ear portion of the equipment frame and the wearer's head.
