These glasses from Hobby Tool Supply provide the viewing power of a handheld jeweller's loupe in a hands free package. Each loupe can be flipped up independently allowing a quick change from regular viewing to magnified viewing. Each loop features an attached, independent swivelling LED light source so you can work even in dim lighting (each light requires two CR2016 batteries, included). The high magnification provides a short focal length and consistent viewing angle.
Loupes are used in a number of industries, notably the jewellery trade, watchmaking, photography, printing, dentistry, education, ophthalmology, geology, & biology. Amateur naturalists may also find a hand lens or a loupe a useful tool when looking at or identifying species. They are also used in numismatics and stamp collecting.
