Hand-mag′ni-fier.

A lens, usually of doubly convex form, mounted and provided with a handle. They are of various shapes and sizes; some, the smaller ones especially, being round or oval, and adapted to be folded within a case of similar shape, which constitutes the handles, so as to be carried in the pocket. Larger ones are frequently rectangular, and are used as readers. The lens may be of meniscus or concavo-convex form, to adapt it to the sight of the user, having a large field of view, for convenience in reading print or viewing objects which do not require a large magnifying power.
