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.
A hand lens is a simple optical instrument used to magnify small objects, typically consisting of a convex lens held in a frame. The unit of measurement for magnification, often referred to as "power," indicates how many times larger an object appears through the lens compared to viewing it with the naked eye. For example, a hand lens with a magnification of 10x makes objects appear ten times larger. This tool is commonly used in fields like biology, geology, and forensics for close examination of specimens.
