Bausch & Lomb Folding Pocket Magnifiers are available in a wide range of powers from 3x to 20x with several styles offering two or three lenses providing varying focal lengths and magnification powers. By combining lenses, three different powers are available with the two-lens models and seven different powers with the three-lens models. The glass lenses used in all folding pocket magnifiers provide durability for long life. The durable plastic swing-away case not only provides a protective cover for the lenses, but serves as a handle as well.
