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 it is not only the elderly who face the difficulties of poor vision - they are increasingly found in middle-aged and even very young segments of the population, and such a 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, of which there are currently many types.

It should be immediately noted that the described device is not a means of complete 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 their functionality, loupe 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 classic 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, embroideries with small black beads on the same dark background), watch repair and jewelry repair, ultra-fine engraving, assembly / soldering of microcircuits and small parts, and, of course, reading small texts (usually , from the technical sphere this can include, for example, the marking of transistors on electronic circuit boards).
At the same time, one should not think that only people with poor eyesight need such devices - they will be an indispensable 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 with contact lenses. The frames used in loupe glasses are securely fixed on the head and do not fall off when the head turns sharply or is strongly tilted. In addition, the hands remain constantly free to perform small operations. Summing up, we can say that the main purpose of such devices is the free performance of painstaking work by a person without undue strain on the visual organs.
The base of the binocular is made up of magnifying lenses that provide a wide viewing angle. To expand the capabilities of the device, LED lighting can be integrated into the tool frame. The on/off switch is often located on the left arm. Standard adjustment along the vertical axis is up to sixty degrees, and along the horizontal axis - up to twenty-five. Typically, the device is powered by AAA or AA batteries.The total weight of the tool with batteries is approximately one hundred grams.
They can be classified according to the type of attachment. To date, the following structures are commonly used:
Separately, cosmetic binoculars can be noted, with the help of which dermatologists scrupulously examine the surface of the skin. They are needed for cosmetic surgeries, such as electrolysis, eyelash extensions, and laser tattoo removal.
By type, these tools are divided into only two categories - regular and illuminated.
First are most suitable for everyday use and are very similar in design to corrective glasses. They have a comfortable frame, have a nose pad made of silicone, the design includes traditional temples. All that distinguishes them from classical models is optical elements (lenses) that have a multiple magnification effect. Such models are widely used by philatelists and numismatists, needlewomen, radio amateurs and, of course, pensioners.
Second devices have a complex design, equipped with a backlight, and are designed for professional activities. The backlight is intended for local illumination of the working area, the loupe glasses themselves come with several sets of interchangeable lenses. The illumination process is carried out by means of batteries. Tools of the second type can be folding and head-mounted.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 conventional household ones, so it is not advisable to purchase them for home use due to the lack of need for most of their functions.
Most regular users of loupe glasses highlight the following undoubted advantages:
IMPORTANT! This tool can be used in conjunction with regular glasses or contact lenses. This factor is especially important for those people whose eyesight is already in critical condition. And the combination of two optical devices will ensure the transmission of the highest quality image for the eye.
The existing shortcomings of the equipment in question, its regular users include the following:
However, the number of "pluses" significantly exceeds the number of "minuses" (and 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 your eyesight.
This product can become absolutely indispensable for people who, due to age-related characteristics, have begun to lose their sight. It is perfect for doing many routine household chores - from banal reading to threading a needle. The main effect of the use of these glasses is the relaxation of the muscles of the eyeball, which means not only the preservation of the current level of vision, but even its slight improvement.Ophthalmologists note that after using loupe glasses, most patients noted an improvement in well-being, the absence of fatigue and tension, as well as a multiple reduction in pain and pain in the eyes. Confirmation of these words of the patients was also recorded during the annual examinations, in which in 15% of cases noticeable improvements were detected.
The optics industry today produces quite a lot of models of magnifying glasses of various types. A potential buyer, when making a purchase, must pay close attention to a number of basic operational characteristics, such as: design features, optics 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, changing 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:
You can also note the manufacturers of the "middle hand", the goods from which can also become reliable assistants: "Ash Technologies", "Rexant", "Bigger", "Schweizer"
An excellent sample for home use: provides excellent magnification of the picture, while relieving eye strain. All small items become visible more clearly and better, this device will be an indispensable assistant when sewing. May be used with contact lenses.
