Hands free magnification. Used by Jewelers, Lab Technicians, and all sorts of crafty folks.
Update on the classic head magnifier. Has 2 bi-lenses (2nd lens flips down from inside) and 1 loupe, allowing for 4 levels of magnification from 1.5x to 7.5x. LED lighting built in uses 2x AAA batteries (not included). Adjustable strap with dial control. Magnification loupe can be installed on either side for extra left or right eye magnification.
