Headworn design: The hands-free magnifying glass with lamp is an ergonomic spectacle frame, which can effectively prevent the eyeglass from falling and reduce the pressure on the bridge of the nose. It is light in weight and will not slip, ensuring firm wear and reducing fatigue during long-term use. You can also free your hands and focus on the object you want to observe. Interchangeable lenses: our eyelenses with magnifiers are packaged with 4 sets of magnifiers: 10x/15x/20x/25x, which can meet your needs for close working. It is recommended to select a lens tube with appropriate magnification according to the size of the object to be observed. Magnification can be quickly interchanged and placed in the corresponding lens storage box to keep it clean. Single eye observation: We recommend using only one eye of the binocular jewelry magnifying glass to observe objects, because when two glasses are used at the same time, the focus will be lost. You can use the two lenses alternately to eliminate visual fatigue and effectively improve work. Please note that this illuminated magnifying glass is suitable for working at close range. Please observe the object close to the target. Removable: The bracket and headband are interchangeable, and both can be securely worn to reduce fatigue during long-term use. And the adjustable magnifying glass bracket can be turned up and down. You can turn it to the desired position to ensure that the eyeball is in the middle position and you can see the details more clearly. Before using, it is recommended that you flip the front lens up to use a single lens.
