Magnifying glass

Not just for reading but also to be used in personal care and medicine Magnifying glasses utilized. There are different types of magnifying glasses that are used differently depending on the area of ​​application. They are primarily used to better recognize possible changes or help to work more precisely through more detailed vision.

What is a magnifying glass?

The German term magnifying glass comes from the French word 'loupe'. In the broadest sense, this is a magnifying glass that is used in a wide variety of areas.

The job of the magnifying glass is to make things easier to read or identify. There are different types of magnifying glasses that are adapted to the respective areas of use. A magnifying glass enlarges an object when it is in its focal length.

Another term used for the magnifying glass is Magnifying glass. This is due to the shape of a magnifying glass, which bundles the heat when sunlight falls and can ignite inflammable materials such as paper. This applies to almost every type of magnifying glass, but depends on the one hand on the diameter of the lens and on the other hand with the ignition temperature of the fuel.

Since numerous cases have been documented in which a decorative convex lens set shop window contents on fire, magnifying glasses that are exposed to sunlight should always be provided with protective covers. This also applies to standard magnifying glasses that are used privately in everyday life.

Shapes, types & types

There are magnifying glasses or magnifying glasses of various types and shapes in almost every household. As a rule, the convex lens has a frame, a frame or a handle. The type of socket used depends on the type of purpose and use.

For personal hygiene, for example, there are hand mirrors or mirrors that can be set up. Most of these mirrors can be rotated, so they can be used on both sides. One of the two sides often has an enlargement effect. In addition, you can find magnifying glasses with light in stores and those that can be worn around the neck so that you can work largely freehand. There are also more special constructions such as tweezers with attached magnifying glasses, which in some cases also have LEDs built in. This is to facilitate use.

In medicine, among other things, magnifying glasses or detailed magnifying glasses are used. This is particularly often the case with dermatologists, who literally have to take a closer look at skin changes. But magnifying glasses are also used in dentistry.

Medical magnifiers are usually more accurate than those used in everyday life, as the work often has to be more detailed. Accordingly, the glasses are built into a wide variety of devices so that they can be used by medical professionals from different fields.

Structure & functionality

A magnifying glass magnifies objects that lie between the glass itself and the focal point of the magnifying glass; thus objects beyond the viewer's point of view. This area between the magnifying glass and its focal point is called the focal length. The effect is related to the different accommodation of the eye. Experts refer to the adaptation of the eye or its refractive power as such. It determines the sharp image of the object that is thrown onto the retina, which regulates far-sightedness with a magnifying glass, while it has no effect on myopia.

The construction of this virtually created image - the enlarged image of the object - is carried out via the convex shape of the glass and two quasi-imaginary rays that emanate from the object. The first ray goes through the center of the glass and is hardly refracted, while the parallel ray goes through the focal point of the lens. This refraction of light is processed differently by the observer - namely in a straight line, not at the angle at which the refraction actually takes place.

Although the subject appears enlarged, the point the eye focuses on appears to be further away. The magnitude of the magnification can be calculated physically.

Medical & health benefits

Magnifying glasses serve various purposes in daily personal hygiene. On the one hand, magnifying mirrors are used to better recognize and remove impurities in the face. The same goes for unwanted hair. Such a magnifying glass can be helpful when plucking your eyebrows or removing other annoying hair. Apart from that, he can help with the application of make-up, as more precise work is possible with the help of a magnifying glass.

For the same reason, the said tweezers with a magnifying glass frame can be found in stores. On the one hand, they are used to pluck annoying hair, but they can also help to remove smaller splinters that have pushed themselves under the skin.

In many cases, magnifying glasses are also used by people whose precise vision can no longer be guaranteed with glasses. Think of reading magnifiers, for example.

Detail magnifiers, which are used in the medical field, are primarily used by doctors to better perform detailed work. This is particularly the case with dentists, for example when precise drilling is required.

On the other hand, general practitioners use magnifying glasses to examine skin changes more closely. This means that any bumps, spots or changes are more noticeable. This helps the medical professional to make a more precise diagnosis, as many things turn out to be too imprecise or difficult to see with the naked eye.

Ophthalmologists also use magnifying glasses to examine the retina, for example. In every doctor's practice you will find magnifying glasses that are used in a wide variety of areas.
