FEATURES HEAD-MOUNTED DESIGN: Our head-mounted magnifier with LED light is used for close viewing. The head mounted hands-free magnifier is an ergonomic eyeglass frame that effectively prevents the magnifier from falling and reduces pressure on the bridge of your nose. It is lightweight and does not come off easily, ensuring a secure fit and minimizing fatigue during long periods of use. INTERCHANGEABLE LENSES: Our head-mounted magnifiers are packaged with 4 sets of interchangeable lenses: product magnification: 10x 15x 20x 25x, which can meet your needs for close-up work. It is recommended to select the appropriate magnification lens tube according to the size of the object to be observed. The magnification can be changed quickly and placed in the corresponding lens organizer to keep it tidy. Monocular Viewing Function: We recommend using only one eye of the binocular magnifier to view an object, as the focus will fail when using two pairs of glasses at the same time. You can alternate between the two lens barrels to eliminate visual fatigue and effectively improve your work. PLEASE NOTE: These magnifying glasses with light are suitable for close up work, please get close to the target to view the object. MULTIFUNCTIONAL APPLICATIONS:This lighted head magnifier has a wide range of usability and is perfect for close up work such as reading, watch/circuit repair, crafts, jewelry identification, eyelash extension, soldering, painting and more. It's perfect for helping watch repairers, jewelers, the elderly, and short-sighted or shortsighted people look at nearby objects.
