OcuLens Telesight Clip-On Magnifier Monocular is a convenient, hands free magnifier that attaches with ease to most eyeglass frames.
Once attached, the interchangeable 5x and 7x lenses can be used to examine objects very close up, and HANDS FREE.

Simply flip down and move the fully adjustable lens to get the best view possible when in use. When no longer needed, simply flip up the magnifier and it will be out of the way. Can be used with either eye. Because of the high power the work distance is short.
Great for inspection of small parts.
