Carson's MagniView handheld magnifier utilizes a classic design with some subtle improvements. The ergonomic top-mounted thumb rest on the handle promotes a more natural hand position, creating balanced weight distribution between lens and handle. There is also a 4.5x spot lens molded into the main lens to give you extra magnification power for fine details when you need it. The 3.5" lens is made of high quality acrylic, which has the benefits of being lightweight, shatterproof, more resistant to scratching, and provides a crystal-clear, distortion-free viewing area. The MagniView handheld magnifying glass by Carson Optical is great for reading small print, inspecting stamps and currency, getting a better view of your needlework or other craft projects, and any other hobby or task that requires attention to detail. With its sleek, unobtrusive design, these magnifiers make the perfect addition to any desk, workbench or crafting table. They are also light enough to take with you on the go.
