Clip-on magnifiers are designed to provide spectacle wearers with hands-free magnification. They are lightweight, hands-free, and fit most eyeglass frames (Bridge: 25mm, Jaws open 15mm). The lens is set 2 inches from the eye, allowing for a more comfortable working distance and when they are not needed, the lens can be flipped up and out of the way. These lenses are interchangeable for different magnification needs.
