Handheld magnifiers are portable optical devices designed to enlarge images for easier viewing. They typically consist of a convex lens mounted in a frame, often with a handle for comfortable use. These tools are commonly used for reading small print, examining details in artwork, or inspecting intricate objects. Available in various sizes and magnification levels, handheld magnifiers can be made from glass or plastic. Some models include built-in LED lights to enhance visibility in low-light conditions. They are popular among individuals with visual impairments, hobbyists, and professionals in fields like jewelry and watchmaking.
