Bausch & Lomb Coddington Magnifier 81-61-31 features a swing-away, nickel-plated case that protects the lens and serves as a handle.  Correction in the Coddington magnifier is achieved through the use of a single thick lens with a central groove diaphragm.  This provides for sharp, crisp images. 

A little trivia ... "Coddington" Magnifiers got their name from their British inventor, Henry Coddington.
