Human eyes only can properly focus to approximately 6-8" (focal length) in front of them; as you get closer than that distance, the image often gets distorted and blurred as our binocular vision is not designed for such close distance viewing. Magnifiers and Loupes assist in allowing your eyes to focus at a closer focal length at a distance beyond human eye capability. A magnifier or magnifying glass uses a convex lens (a thinner lens at the edges and thicker at the center) to magnify. A convex or bi-convex lens shape bends light rays inward, enabling an enlarged view when looking through the lens. A traditional magnifier has a round-shaped lens secured in a frame that holds the lens and handles, allowing the user to keep it at a comfortable distance and its focal length. The magnifying lens can also bend light rays inward to converge sunlight to create an area of radiation and intense heat that can easily ignite a fire.

Handheld magnifiers are one of the most common types of magnifiers available. The hand-held magnifier typically has a handle that is attached to a lens through which the user will view an object - whether it is text or an image. Because the user has the ability to adjust the distance between the lens and the object. A Coddington magnifier is a magnifying glass with a single very thick lens with a central deep groove diaphragm at the equator that limits the rays to those close to the axis minimizes spherical aberration. This allows for greater magnification than conventional magnifying glass that typically has 10x up to 20x magnification.

A stand magnifier is basically a plus lens mounted on legs that fix the distance from the lens to the object. They work based on the principles of angular and relative distance magnification.

Loupes or hands-free magnifiers are optical lenses held close to the eye which is used for viewing objects with some moderate magnification. In contrast to a magnifying glass, a loupe is used at a close distance from the eye, is typically smaller, and has a shorter focal length. Loupes may be used to inspect optical elements, e.g., before and after cleaning operations and other types of small objects, e.g., in jewelry, biology, electronics, and watchmaking. Specialized loupes, often of binocular type, are used in surgery and dentistry.
