What is a magnifier used for?

A magnifying glass (called a hand lens in laboratory contexts) is a convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle (see image). A magnifying glass can be used to focus light, such as to concentrate the sun's radiation to create a hot spot at the focus for fire starting. A magnifier can be used in many ways in our daily life. But, firstly, let’s find out the function of magnifier tool.

WHAT IS THE FUNCTION OF MAGNIFIER TOOL?

The magnifying tool is used to change the zoom level of your working image. If you only click on the image, the zoom is applied to the whole image. But you can also click-and-drag the mouse pointer to create a zoom rectangle. Magnifying glasses make objects appear larger because their convex lenses (convex means curved outward) refract or bend light rays, so that they converge or come together. In essence, magnifying glasses trick your eyes into seeing something differently than it really is.

When light bounces off an object and travels to your eyes, those light rays travel parallel to each other. When they pass through a magnifying glass, the convex lens bends the parallel rays so that they converge and create a virtual image on your eyes' retinas.

That virtual image on your retinas appears larger than the real object due to principles of geometry. Despite the magnifying glass, your eyes trace the light rays back in parallel lines to the virtual image. Since the virtual image is farther from your eyes than the object is, the object appears bigger!

A sheet magnifier consists of many very narrow concentric ring-shaped lenses, such that the combination acts as a single lens but is much thinner. This arrangement is known as a Fresnel lens.

VISION AIDS

Magnifying glasses are often used to help people with vision problems. Eyeglasses are a form of magnifying glasses, which correct problems ranging from near-sightedness and far-sightedness to astigmatism. People with macular degeneration, or eye problems caused by glaucoma or diabetes, often use hand-held magnifying glasses to read books, newspapers and other documents with fine print. Magnifying glasses mounted in reading devices that can magnify print from three to 10 times its normal size are also useful for people who have eye diseases like rod and cone deficiencies or retinitis pigmentosa.

SCIENTIFIC AND MEDICAL TOOLS

Magnifying glasses can be mounted on stands to form microscopes, which scientists like chemists and biologists use to perform research. Microscopes are also used in medical research, and in medical labs for testing blood and other bodily fluids and tissues. Microscopes can magnify objects thousands of times, making it possible to see organisms and elements of different types of matter that cannot be seen by the naked eye. Some microscopes are fitted with cameras that record these magnified images.

PROFESSIONAL TOOLS

HOME AND HOBBY AIDS

Magnifying glasses are also useful for reading details on maps and for reading fine print on legal documents.Coin collectors use magnifying glasses to detect the wear of a coin, which helps determine its value.
