What it is?

It should immediately be noted that magnifying glasses are not a means for cardinal vision correction, but an auxiliary ophthalmic accessory for household use, as well as for use in some professions related to the examination of small details and objects . A modern optical device is a good way out of such situations.

Magnifying glasses combine the characteristics of ordinary glasses and a magnifying glass, at the same time they have a shape almost like ordinary glasses, which does not cause discomfort when using them, and lenses like a magnifier provide multiple (up to 160%) magnification, which is impossible with ordinary glasses.

Why do we need it?

The device is not intended for permanent wear . It should be used in situations where it is impossible to consider something without his help, or you need to do painstaking work. This can be reading indistinguishable text, some types of needlework (for example, embroidery with black beads on a dark background), minor watch repairs, jewelry work, fine engraving, manual assembly of electronic devices and microcircuits, and something else like that. For a person with excellent vision, this is an indispensable assistant, but they are also suitable for problematic visual acuity. Visually impaired people may wear the device over their glasses or contact lenses.

At the household level, magnifying glasses will allow an elderly person with low vision to easily thread a sewing needle, see a doctor's prescription, read the instructions for the medicine, replace the battery in the watch and even pull out an accidental splinter without calling anyone for help. Wherein The magnifying glasses hold firmly on the face and do not fall off when the head is tilted or when the head is turned to the sides, and the hands remain free to perform various operations.

With magnifying glasses, you can do complex painstaking work without strain on the eyes.

How to choose?

The optical industry produces various types of magnifying glasses. When choosing, several distinctive factors are taken into account: functional purpose, design features, materials of manufacture, optical parameters. The performance properties of magnifying glasses are characterized by the values on which the choice of accessory depends.

  • Working distance . This is the size of the space between the object of interest and the lens. The size of the working distance must be selected based on the type of operations performed. If you plan to use tools, then for comfortable work you will need a product with a large working distance in order to freely perform additional manipulations. If you intend to thoroughly examine small objects with the help of magnifying glasses, then models with a small working distance will do.
  • Line of sight . This is the area of the object visible through the lens. The field of view decreases with increasing multiplicity of the device.
  • Magnification factor … This indicator is different, and its choice directly depends on the planned use of the product. For daily work in jewelry or radio engineering workshops, the maximum magnification is required, and for domestic use, you can choose a model with a lower magnification.
  • Focal length . This is the distance between the lens and the human eye that maintains full coverage of the field of view. The longer the focal length, the higher the comfort when using magnifying glasses, the more expensive the product is.
  • Depth of field . This is the distance between the nearest and distant points of the object in question, where the focus is not lost. The depth of field decreases as the magnifying glass increases in power.

The choice depends on what the buyer intends to do with the use of such glasses.

These characteristics are interrelated, changing the values of some directly affects the values of other optical parameters . When choosing, the buyer decides for himself what is more important for him in accordance with the specific purpose of the device and his preferences. If you have made a firm decision to try magnifying glasses, then you definitely need to choose not the cheapest option so as not to buy a fake. It is naive to believe that a budget model of magnifying glasses will meet the expectations of good quality in use.

The final decision to purchase this new item also depends on the character of a particular person. There are people who are always ready to experiment and willingly test something new. They are optimists in life and will be able to appreciate the real benefits of magnifying glasses, and the design flaws noticed will not cause them serious grief. Such people can safely buy magnifying glasses, they will be satisfied. But there are many who are initially skeptical and focus on the shortcomings.

Such people should not rush to buy.

Despite the noted shortcomings, most buyers recommend this new product to everyone with vision problems, since the real benefits of using it significantly outweigh the negative points … It is necessary to use magnifying glasses strictly according to the recommendations of ophthalmologists, otherwise, instead of being useful, the device may harm. It must be remembered that when working with magnifying glasses, obligatory breaks are required in combination with simple gymnastics for the eyes so that the visual system periodically gets rest. If you use the accessory with reasonable care, exactly following the recommendations of experts, then there will be no problems.

Harm is possible solely through the fault of the user, when he ignores the rules of application and does not comply with the time limit for breaks. As a result, overloads of the visual system occur with negative consequences.
