This is truly one of the finest magnifiers Bausch & Lomb has to offer. Hastings Triplet Magnifiers incorporate three separate glass lenses, bonded together to form a compound lens to provide sharp, very distinct magnified images without distortion—even under 14 and 20 power magnification.
A swing-away, nickel-plated case protects the lens and serves as a handle.
