pocket magnifier

Pocket magnifiers cover a wide range of powers, typically from about 2× up to 45×. Common options you’ll see include 2×, 3×, 7×, and 15×.

Lenses are commonly made from acrylic or high-grade glass. Several models also include a built-in spot lens for extra power—examples of spot-lens magnifications include about 4.5× and 6×.

Keychain and retractable magnifiers typically use a spring-loaded pop-up or extend mechanism and include a durable keychain connection so they can attach to keys, bags, or pockets for quick access.

Lens diameters vary widely, from very small keychain sizes like 0.7 in. to handheld lenses around 3.5 in., up to larger options such as a 50 mm premium acrylic lens—covering sizes from tiny to several centimeters across.

Weights range from about 0.02 pounds up to 0.5 pounds, with many compact and keychain options weighing well under 0.2 pounds.
