The PO-55 5x MiniBrite Pocket Magnifier from Carson Optical is small, inexpensive pocket viewer that can help make reading everyday small items much easier. The slide-out lens is guarded by a protective plastic sleeve and illuminated by a bright LED light powered by three "AAA" batteries (not included). The lens produces a bright distortion-free image. When not used, collapse it and stuff it your shirt pocket. It's lightweight, easy to use and very functional.
