Magnifying glasses. Features: Magnifying glasses are the perfect companion for people who work with small objects. The lenses are fixed on the glasses frame, leaving both hands free for reading, scrutinizing pictures, needlework, modeling, high-precision work with clock mechanisms, jewelry or microchips, etc. These magnifying glasses are great for either professional or daily work. Magnifying glasses are equipped with interchangeable lenses. If you want to increase the magnification power, just change the lenses. There are three available magnifying powers: 1.5x, 2.5x and 3.5x. The lenses are fixed with an easy holder clip, which firmly holds the magnifier in the selected position.
