Freeviewer's Assistant Headstrap for hands free 3D Viewing

This is an adjustable headstrap for long term or hands free use of the One-eye stereo viewer (now called the Freeviewer's Assistant). To use it for over/under pairs simply orientate it in the vertical position. Use without the headstrap for a portable viewer that will fit in your pocket or purse! It attaches to the viewer using hardware and uses velcro for the head attachment. The 1i headstrap comfortably and securely fits users of any size, allowing users to enjoy the Freeviewer's Assistant for long periods of time with ease. With its adjustable strap, the 1i headstrap provides a custom fit that keeps the Freeviewer's Assistant in place.
