Headworn design: The headworn hands-free magnifying glass is an ergonomic glasses frame, which can effectively prevent the magnifying glass from falling and reduce the pressure on the bridge of the nose. It is light in weight and does not slip, ensuring that it is firmly worn and reducing fatigue during long-term use. You can also free your hands and focus on the object you want to observe.Replaceable lens: Our headwear magnifying glass package includes 8 sets of replaceable lenses: 2.5x/4x/6x/8x/10x/15x/20x/25x, which can meet your needs for close work. It is recommended to select the lens tube with appropriate magnification according to the size of the object to be observed. The magnification can be exchanged quickly and put into the corresponding lens storage box to keep it clean. Monocular observation: We recommend using only one eye of the binocular magnifying glass to observe the object, because focusing will fail when using two pairs of glasses at the same time. You can use two lenses alternately to eliminate visual fatigue and effectively improve your work. Please note: this magnifying glass is suitable for close work. Please observe objects close to the target. Removable: The bracket and headband are interchangeable, both of which can be firmly worn and reduce fatigue during long-term use. And the adjustable magnifying glass bracket can be turned up and down, and can be turned to the desired position to ensure that the eye is in the middle position, and the details can be seen more clearly. Before use, it is recommended that you turn the front lens up and use a single lens. Multi-functional application: The head-mounted magnifying glass with light has wide availability and is very suitable for close work, such as reading, watch/circuit maintenance, handicrafts, jewelry identification, eyelash extension, welding, painting, etc. It is very suitable for helping watch repairers, jewelers, the elderly, nearsighted or nearsighted people observe nearby objects.
