The development of modern technologies by "leaps and bounds" permanently leads to the fact that in many professions people have to work with small objects, which causes additional stress on the organs of vision. Unfortunately, today, not only the elderly are faced with the difficulties of poor vision - they are increasingly found in their middle-aged and even very young segments of the population, and this trend is difficult to ignore.
At the same time, some professional industries in which a person works with small objects - from medicine to jewelry - require improved visual qualities. It is possible to achieve the desired result with the help of special magnifying glasses, which currently exist in many types.

It should be noted right away that the described device is not a means of full-fledged vision correction, but only carries the function of an auxiliary ophthalmic accessory for professional and domestic use. Such glasses may be needed both for reading texts written in small print (for example, instructions on various aerosols), and for full-fledged operations with small objects (for example, watchmaking).
In terms of functionality, magnifying glasses are a combination of a magnifying glass and standard ophthalmic eyepieces, respectively. For ease of use, they have a universal frame, but their lenses have a diopter for multiple magnification (up to 160%), which is absolutely impossible to find in classical devices. Moreover, with such an increase, the constant wearing of such optics will only lead to a deterioration in vision and the development of myopia.
Therefore, this optical device should be used only once and in certain situations when it is impossible to perform any painstaking work without its help. This includes some types of needlework (for example, embroidery with small black beads on the same dark background), watch repair and jewelry repair, ultra-thin engraving, assembling / soldering microcircuits and small parts, and, of course, reading small texts (as a rule , from the technical sphere, this includes, for example, the marking of transistors on electronic boards).
At the same time, one should not think that such devices are needed only for people with poor eyesight - they will prove to be an irreplaceable assistant for all categories of people.At the same time, people with vision problems can wear loupe glasses over their regular glasses or use them together with contact lenses. The frames used in magnifying glasses are securely fixed on the head and do not fall off when the head is turned sharply or when the head is tilted. In addition, hands remain constantly free to perform small operations. Summing up, we can say that the main purpose of such devices is the free performance by a person of painstaking work without undue stress of the visual organs.
The binoculars are based on magnifying lenses that provide a wide viewing angle. To expand the capabilities of the device, LED illumination can be integrated into the tool holder. Its on / off switch is often located on the left arm. The standard adjustment on the vertical axis is up to sixty degrees, and on the horizontal axis up to twenty-five. Usually the device is powered by AAA or AA size batteries. The total weight of the tool with batteries is approximately one hundred grams.
They can be classified by the type of attachment. Today, the following designs are commonly used:
Separately, we can mention cosmetic binoculars, with the help of which dermatologists scrupulously examine the surface of the skin. They are needed for cosmetic operations, for example, electrolysis, eyelash extension, laser tattooing.
By types, these instruments are divided into only two categories - conventional and backlit.
The first are most suitable for home use and are very similar in design to prescription glasses. They have a comfortable frame, have a nose pad made of silicone, and are designed with traditional temples. All that distinguishes them from classical models is the optical elements (lenses) with a multiple magnification effect. Such models are widespread among philatelists and numismatists, needlewomen, radio amateurs and, of course, pensioners.
Second the devices have a complex design, backlit, and are intended for professional use. The backlight is intended for local illumination of the working area, the magnifying glasses themselves have several sets of interchangeable lenses in the kit. The backlighting process is carried out by means of battery cells. Tools of the second type can be folding and forehead mounting. They are quite common in medicine (dentistry, microsurgery, vascular surgery) and among specialists in radio engineering and electronic equipment, jewelers and watchmakers. Backlit devices are much more expensive than ordinary household appliances, so it is not advisable to purchase them for home use due to the lack of the need for most of their functions.
Most of the regular users of magnifying glasses highlight the following undoubted advantages:
IMPORTANT! This tool can be used in conjunction with ordinary glasses or contact lenses. This factor is especially important for those people whose vision is already in critical condition. And the combination of two optical devices will provide the highest quality image for the eye.
The existing disadvantages of the considered equipment, its regular users include the following:
However, the number of "pluses" significantly exceeds the number of "minuses" (and even those of a technical nature), so if a person really needs such glasses for work or for home use, then it is better to buy them than to continue to worsen their eyesight.

These products can become completely irreplaceable for people who, due to age characteristics, have begun to lose their eyesight. It is perfect for many routine household chores - from banal reading to threading a needle. The main effect of using these glasses is to relax the muscles of the eyeball, which means not only maintaining the current level of vision, but even improving it somewhat. Ophthalmologists note that after using loupe glasses, most patients noted an improvement in their well-being, lack of fatigue and tension, as well as a multiple reduction in cramps and pain in the eyes. Confirmation of these words of patients was recorded during annual examinations, in which in 15% of cases noticeable improvements were revealed.
The industry in the field of optics today produces a lot of models of magnifying glasses of various types. When making a purchase, a potential buyer must pay close attention to a number of basic performance characteristics, such as: design features, optical parameters, functional application. At the same time, the choice must be made based on the following very specific values:
All of the above values are interrelated, therefore, a change in some values will affect others.
All over the world, the following brands are especially popular, having long and positively proven themselves in this specific segment of the optics market:
It is also worth mentioning the producers of the "middle hand", whose products can also become reliable assistants: "Ash Technologies", "Rexant", "Bigger", "Schweizer"
Perfect for home use: Provides excellent picture magnification while relieving eye strain. All small objects become visible more clearly and better, this device will be an indispensable assistant when sewing. Can be used in conjunction with contact lenses.
