OPTIVISOR HEADBAND MAGNIFIERS feature high quality, glass lenses, a padded leather headband, a dial adjustment to fit any size. An adjustable pivot assembly can be tightened to hold the visor in place. Lens plates are interchangeable.
When purchasing an Optivisor, it is more important to look and the working distance than the magnification power of the lens. Optivisors do not have very strong lenses, but they can focus at very short distances. We recommend you work in a comfortable position and measure the distance from your eyes to the work, then compare that to the working distances on the Optivisors. Your work will then be in focus without you moving in or away.
This Optivisor will focus 10" from your eyes. If it is comfortable for you to work on items at this distance, this is the magnifier for you.
