With a hand lens, you cannot change the power of magnification, while with a microscope, you can change the power of the magnification. With a hand lens, only one lens is used to magnify an object, while a compound microscope uses two lenses (one in objective lens, one in eyepiece).

The term "hand lens" is derived from the combination of "hand," referring to the act of holding the lens in one's hand, and "lens," which comes from the Latin word "lentil" or "lens" meaning a lentil-shaped convex glass. The hand lens is a small, handheld magnifying glass used to observe objects up close.
William Julliano invented the first hand lens in 1991
The upper outside "corner" of each lens hooks into the frame, and the inside edge of the lens (at the nosepiece) slides in and out. To remove the right lens, hold the frame with your left hand, left thumb on the top of the frame over the nosepiece, and left index finger between the two nose pads. Hold the right lens with your right thumb on top and right index finger underneath, close to the nosepiece, and pull the inside edge of the lens out and away from the frame while pressing slightly with your left thumb against the top of the frame, and pulling slightly with your left index finger (this is the bending action you probably remember). The lens will pivot at the outside corner, where it's hooked in, until you pull it free. Change your grip and repeat on the left side.
