Modern reality literally riveted our eyes to the screen: in the office it is a computer monitor, at home - a TV set or all kinds of gadgets, without which we can no longer imagine our vacation. In principle, this is just a tribute to progress, which has become not only a habit, but also a part of our life. Everything would be fine, but even the most modern monitors continue to have a negative impact on the level of vision and eye health in general.
To maintain the health of the eyes of people who spend a long time in front of a computer monitor, special protective glasses were invented for working at a PC.

Before figuring out how to correctly approach the choice of glasses, let's figure out why they are still needed.
Manufacturers of monitors and TVs unanimously convince buyers that the screens of their gadgets are absolutely safe for eyesight. In general, it is so. However, the decisive factor in the impact on the health of the eyes and the level of vision is not the radiation itself emanating from the screen, but the duration of its exposure. People whose work is extremely closely related to the long-term perception of the image on the monitor, almost everyone notes eye fatigue, dryness in them, blurred vision when looking at distant objects. This is all related to the following:
Prolonged concentration and work with high-contrast images, be it text or graphics, over time leads to rapid eye fatigue, which are in constant stress.
This includes no or extremely short interruptions, improper lighting and monitor placement, and fewer blinks. All this causes excessive tension in the muscles of the eyes, and subsequently can cause dry eye syndrome. It manifests itself in a burning sensation, a sensation of the presence of a foreign body in the eye ("sand"), dryness or, conversely, increased lacrimation. The listed symptoms, if ignored for a long time, can lead to irreversible changes and require drug treatment.
According to the norms, the monitor should be located at a distance of at least 60 cm. However, in the process of work, almost everyone unconsciously moves closer to it. Due to this, computer visual syndrome can develop. It manifests itself in a violation of the mobility of the lens. Its essence lies in the difficulty of focusing when looking at a distant object. Also, its symptoms include temporary clouding, photosensitivity, and the appearance of flies.
As you can see, many vision problems can be avoided by observing all norms, taking timely breaks and gymnastics for the eyes. But this is an idealized version that almost no one can translate into reality. Most, whose work is directly related to sitting at the monitor, do not even follow half of the rules. It is for them that PC goggles will be a real salvation.
Special glasses for PC work do the following:
As you can see, safety glasses can make time spent at PCs and gadgets more comfortable for more hours without unpleasant consequences for eye health. To choose high quality glasses, you need to know the following about them:
They can be made of glass or polymer. The former are more resistant to mechanical damage, scratches, block UV radiation, and more accurately transmit diopters. However, they are heavier and can break. Polymer durable, lightweight, can be of various shapes. The disadvantages are inaccurate diopter adjustment and incomplete UV protection.
By structure, monofocal, bifocal and progressive are distinguished.
Monofocal lenses are designed for people without visual impairments (myopia, hyperopia, etc.).
Bifocal zones have 2 clearly visible zones: the upper one, for looking at the PC screen, the lower one, for working with text and other objects outside the monitor. Designed for people with presbyopia (visual impairment at close range) and are selected by a specialist.
Progressive ones are the most difficult and expensive. They allow you to work at the PC, and also without taking off your glasses, it is good to see distant objects and nearby objects. Designed for people who have vision problems and are selected only by an ophthalmologist.
Glass lenses can only have an anti-reflective coating. For polymer products, the choice is much greater:
In addition to these types of coatings, some manufacturers offer lenses that increase contrast or improve color rendering. In addition, there is a multifunctional coating that combines several of the above characteristics.
It can be made of plastic, metal, and a combination of both. This characteristic does not affect image quality, but it may affect comfort. So, if you have lenses with large diopters, then it is better to put them in a plastic frame, because it will reduce the overall weight of the product and will hold them more securely.
As for the design, it can be rim, semi-rim and rimless. The first is the most reliable, suitable for polymer and glass lenses. The second and third can be used only for plastic and, moreover, with small diopters or without them.
So, if you are an office worker, IT professional or a gamer, then the following list of the best glasses for PC work is for you.
