A hand lens typically measures in magnification units, such as 10x or 20x, indicating how much larger an object will appear when viewed through the lens compared to the naked eye.

When you view an object through a hand lens, light rays entering the lens are bent inward, making the object appear larger than it actually is. This magnification effect occurs because the lens converges the light rays, which increases the apparent size of the object when viewed through the lens.

A hand lens is nothing more than a hand-held magnifying glass. The term "hand lens" is used primarily in a laboratory setting. The lens, or glass, is set into a frame with a handle attached. The fictional Sherlock Holmes popularized the hand lens, or magnifyng glass when looking for clues to solve a mystery.
The mass of a hand lens can vary depending on the size and material it is made of. Typically, a hand lens can weigh anywhere from a few ounces to a pound.
The hand lens was invented in the 17th century by Dutch spectacle maker, Zacharias Janssen. He created the first compound microscope by combining lenses in a tube to magnify small objects.
The main parts of a hand lens include the lens itself, the frame or housing that holds the lens, the handle for holding and maneuvering the lens, and sometimes a protective cover or case.
