Glasses with yellow lenses. Production technologies Are glasses with different lens colors good? Reviews from specialists and drivers

Contents of the article: classList.toggle()">toggle

Anti-glare glasses are an accessory necessary for drivers, not only to preserve vision.

They also help to avoid accidents on the road.

Such glasses give a person the opportunity to simply not notice bright glare from reflective surfaces.

Operating principle

To prevent your eyes from being blinded by bright sun glare on reflective surfaces, used in anti-glare glasses polarized lenses . Their action is to filter out the irritant - reflected light. Accordingly, it is also not detected by the human eye.

Another direction of action of this technology is the absorption of rays of the blue spectrum, which is harmful to the eyes. Anti-glare glasses absorb them, and a person perceives only rays of the yellow, safe spectrum.

The advantage of such glasses for vision is that they protect the eyes from ultraviolet radiation . They also help relax the eye muscles, which allows a person to see with more contrast and clarity. These properties are important for eye health.

The result of glasses with polarized lenses is a clearer picture of what is happening on the road. Light glare on wet asphalt, snow, car windows, blinding light from headlights and lanterns are swept away. The likelihood of emergency situations is reduced, which is extremely important.

Who needs it and in what cases?

Anti-glare glasses are created primarily for drivers. They will also be useful for athletes, climbers, fishermen and sailors. When working in any conditions where sharp vision is required, and there are interfering reflective surfaces, anti-glare glasses will be appropriate.

Every driver has to experience discomfort, catching blinding glare.

At any time of the day, irritating factors are present. During the day - reflected sunlight, at night - headlights of oncoming cars and street lights.

The dashboard reflected in the windshield can also be an irritating factor around the clock. Properly selected anti-glare glasses successfully cope with all these problems.

How to choose the right anti-glare glasses

To choose the right anti-glare glasses, you need to analyze the conditions in which you most often drive. Depending on this factor, you will have to decide on the type of glasses.

Glasses with polarized lenses. Fully polarized lenses will be appropriate when driving at night in order to eliminate glare from artificial lighting.

Anti-glare glasses. These glasses have a special strip ( upper part lenses) that neutralize glare. For example, when seeing an oncoming car or in bright sunlight, the driver should tilt his head slightly to protect his vision. Suitable for daytime driving.

Glasses with dark lenses provide the greatest protection.. They neutralize light glare and allow you to relax as much as possible. eye muscles, protect from ultraviolet rays. When there is fog, they make the picture contrast and help you distinguish objects better.

Glasses with yellow lenses universal. They protect against UV radiation, reduce the intensity of glare from snow and headlights of oncoming cars, and give rest to the eyesight. Can be used in any weather and at any time of the day.

Glasses with brown lenses also provide eye protection from ultraviolet rays, dissipate glare from wet surfaces, car headlights, and relieve eye strain.

Suitable for driving in fog, twilight, and bright sunlight.

The frame of anti-glare glasses for drivers should be comfortable so that there is no need to correct them. To do this, you need to pay attention to the quality of nose pads and temples. It is advisable to choose thin ones so that they do not interfere with your view.

Polymer lenses weigh the least and do not break.

Well-chosen, comfortable anti-glare glasses will preserve the driver’s vision and protect him from accidents. You just need to correctly analyze the conditions for which they are required and carefully monitor the quality of the lenses and frames when purchasing.

VISION FEATURES

A person can distinguish surrounding objects only if they are illuminated and the reflected light hits the retina of his eyes. Light represents electromagnetic waves, they cause a visual sensation. Human eyes perceive the colors of the light spectrum differently. Under the same illumination, the perception of red and blue tens of times less than yellow and green. The sensitivity of the eyes to light of different wavelengths is shown by the so-called “visibility curve”. To improve the perception of less distinguishable colors and increase the contrast of vision, light filters are used.
Certain fragments of the solar spectrum have a negative effect on human eyes. It has a visible spectrum (light) and an invisible spectrum - ultraviolet (UV) and infrared (IR).
In most people, under the influence primarily of UV and related radiation - violet, blue and cyan - gradually accumulate destructive changes in the eyes, and vision deteriorates with age.
The most common means of protecting eyes and correcting vision is various glasses, but they must be properly selected.

LENSES AND FILTERS

Glasses are designed to improve vision and protect the eyes, they can be:

  • corrective– correcting visual defects, mainly myopia and farsightedness;
  • protective– protecting eyes from ultraviolet radiation and bright light;
  • corrective and protective simultaneously.

Main part of glasses, which determines the purpose and quality, is with Veto filters or lenses made of transparent materials, fixed in a frame. To protect the eyes from radiation, replaceable filters are sometimes installed on top of the lenses of corrective glasses.
Light filters are plates, films, etc., partially or selectively absorbing various types radiation. Light filters can be flat or convex, but the thickness of the material is the same over the entire surface.
Lenses This optical elements with curved surfaces and different material thicknesses. Changing the shape of the internal and external surfaces of the lenses and the distances between them allows you to obtain the required optical power, measured in diopters. Corrective glasses are equipped with converging (“plus”) and diverging (“minus”) lenses. If necessary, corrective lenses can be given the properties of light filters.
Glass filters and lenses less than plastic ones, they distort objects, provide some protection from ultraviolet light, have high abrasive resistance - they are more difficult to scratch. Unfortunately, they are heavy and unsafe, since if they break, sharp fragments can damage your eyes. Because of more weight glass lenses less comfortable and convenient. In addition, they fog up faster and more if you enter a warm room from the cold.
Plastic filters and lenses They are much lighter and safer than glass analogues, therefore they are widely used in glasses used by drivers. Their main disadvantage is low abrasive resistance. Many clear plastics allow ultraviolet light to pass through.
To improve the properties of light filters and lenses, darkening, anti-reflective, antistatic, water-repellent and surface-hardening coatings are applied to one or both surfaces.
Anti-reflective coatings (AR coatings) are used to eliminate glare and ghost images that create light interference. These are very thin, less than one micron, layers of metal oxides (titanium, zirconium, etc.) that are applied to the surface of the lens. In the presence of such a film, the light reflection coefficient is significantly reduced. The thickness and refractive indices of the coating layers are selected in such a way that the reflected light waves and direct ones who came to inner side the lenses were mutually cancelled. A properly selected antireflective coating reduces reflection from both surfaces of the lens and increases its light transmission. Sunglasses used to reduce light load on vision. To do this, they have filters or lenses with varying degrees darkening, for example smoky gray, distorts color perception less than others.
Quality sunglasses must meet the following basic requirements:

  • dim visible light until comfortable;
  • absorb some of the violet and blue light;
  • almost completely reduce the intensity of ultraviolet radiation;
  • maintain the driver's ability to distinguish information on the dashboard of his car, as well as other vehicles and traffic lights, and road signs, markings, etc.

Sunglasses with “mask” are darkened only in the upper part, which allows you to protect your eyes from direct sun rays and at the same time it is good to see the instrument panel. The disadvantage is that they require the driver to constantly move his head, which tires his vision.
Protective polarized Glasses are recommended for use as sun protection when, after rain or in winter, light is reflected from flat shiny surfaces. The lenses of such glasses have a coating (polarizer), which allows them to cut off the horizontal component of the light wave and, to a certain extent, reduce its intensity.


Anti-headlight safety glasses with yellow and orange filters can be used in cloudy weather and dark time days, as they increase image contrast, color discrimination and clarity of perception. A tinted mirror strip is applied to the upper third of the lens surface. The effectiveness of protection from the headlights of oncoming vehicles with various light sources is associated with their following physical characteristics:
- incandescent lamps emit yellow-white light and contain all wavelengths without exception, but relatively less violet and blue light;
- halogen lamps emit bluish-white light with a significant blue component;
- xenon headlights, the most powerful, emit blue-white light with an even greater violet-blue component.
Anti-headlight filter lenses should absorb most of the violet-blue light from any headlights. The main disadvantage is the same as that of glasses with a “mask”.

Glasses for driving in poor visibility conditions(“all-weather driving” glasses) with yellow filters:

  • completely block ultraviolet radiation harmful to the eyes and increase the contrast of vision due to partial absorption of the violet-blue part of the spectrum;
  • improve color discrimination, transmitting light well in the yellow-green part of the spectrum;
  • relieve drowsiness and fatigue, improve perception external environment due to the transmission of light in the yellow region of the spectrum (the effect of the “sun” against the background of cloudy weather);
  • Like anti-headlight lenses, they reduce glare from oncoming headlights.


Since there are products of dubious quality on sale, it is advisable to purchase glasses in specialized “Optics” stores. Well-known global manufacturers mainly sell their products through them. Any glasses must have a Russian certificate indicating their manufacturer. Branded products must have appropriate packaging with a booklet and company logo stickers on the lens. It would not be superfluous to consult a specialist.
Driver glasses must be light, durable and injury-proof, and their light filters must have sufficient large sizes, to provide protection from light not only from the front, but also from the sides, without distorting objects.
It should be remembered, that any glasses with light filters or light filter lenses absorb part of the light flux and should not be used in low light conditions if:

  • the light spot from the headlights of your own car is reduced so much that it no longer guarantees a timely stop in front of an obstacle;
  • the side lights and brake lights of vehicles ahead become faintly visible;
  • the reflected light from the retroreflectors of standing vehicles is significantly weakened and the idea of ​​the distance to them is distorted;
  • The reflected light from road signs and markings is significantly weakened and their colors change.

Chameleon glasses(the name in everyday life) with photochromic light filters (or filter lenses) are ineffective in the car interior, since its glass almost does not transmit ultraviolet radiation, and it is this that causes the “automatic” darkening of these light filters. In addition, their lenses are made from mineral glass.
Select filters(lenses-filters) for all lighting conditions is impossible, so it is advisable to have several glasses with different properties in the car:

  • sunglasses with gray, gray-green or, best of all, gray-brownish filters that do not distort natural colors (when using corrective glasses, you can use appropriate filters in the form of clip-on attachments);
  • "driver's all-weather" to improve vision when bad conditions lighting - fog, twilight, rain, snow (the correct selection is determined by the fact that, according to subjective feelings, they improve visibility and driving comfort).
  • polarized - as sunscreens, but it should be remembered that they almost halve the luminous flux and cannot be used in low light.

Caring for your glasses boils down to this:

  • glasses, especially those with plastic lenses, must be stored in a durable case with an internal covering made of fabric or leather;
  • glasses should be wiped with a thin and soft special cotton cloth;
  • wash glasses in case heavy pollution a special solution or water and soap (in no case should you use organic solvents);
  • place glasses on any surface with the lenses facing up;
  • It is good to protect glasses from falling with a chain attached to the ears;
  • adjust the fit of the glasses by bending the nose pads and ear hooks (if they are plastic, first lower them into hot water for 15-20 s).

Application polarized glasses is due to the fact that the sun is the enemy of car enthusiasts. Its activity has a significant impact on the driver’s well-being, his attention and reaction speed. It should be noted that even a simple sunbeam can lead to an accident with fatal. That's why driver's glasses are necessary.

Where should you expect danger while driving?

In sunny weather the most dangerous time The period from 11 a.m. to 4 p.m. is considered. The light at this moment is brightest, and ultraviolet radiation is harsher. In the morning and evening time its intensity subsides. However, at the same time, the light begins to shine directly into the eyes of the person who is driving. It hits a person's face at an angle of 45 degrees. The driver begins to squint. Due to this, the viewing angle is reduced. If you do not use special glasses for the driver, then the obstacle can be seen only 5 meters in front of the car.

Standard visors, used as sun protection, do not help in all situations. They will not be able to protect you in a situation where the rays are reflected from a wet road. Naturally, direct light in this case does not pose any danger. But wet asphalt acts as a mirror, reflecting the sun's rays. Accordingly, neither a visor nor a special protective strip on the glass can help.

The danger is posed not only by wet asphalt, but also by straight glass on oncoming trucks and buses. You can become momentarily blind when leaving a dark place. It serves as a garage, tunnel, underground parking. If the driver does not see anything, then he should turn on the emergency lights, stop without changing lanes, and wait until vision is completely restored.

Those glasses for the driver that do not have special UV protection can lead to total loss vision. What is this connected with? A stream of light containing ultraviolet radiation will enter the retina of the eye. This can cause a burn, which in turn will lead to a significant decrease in vision. In such a situation, you can go completely blind.

Improving your vision with glasses

Must be used polarized glasses for drivers who have a special filter. The reflected light will be scattered in them. Accordingly, the overview will improve. A special layer located in the center of the lens will cut off reflected light, making glare almost completely disappear. You can purchase polarized glasses for drivers in automobile stores, in specialized departments for fishing and recreation, and in pharmacies. They are also available to order online. You can feel more comfortable wearing these glasses. In addition to glasses, you should think about the cleanliness of the glass, which glares quite strongly when dirty. It needs to be washed constantly.

An important element for a comfortable ride

Not long ago, special glasses for drivers could only cause a skeptical grin. At first glance, they were no different from simple sun protection ones. In reality, things are a little different. Experts recommend purchasing glasses designed for driving in poor visibility conditions and in too intense light. In order not to make a mistake when purchasing glasses, you need to take your choice seriously. Some design features require attention.

What should the frame be like?

What should you pay attention to first when purchasing anti-glare glasses for drivers? The frame must meet some basic requirements. The driver should feel comfortable wearing glasses and not experience any negative sensations. Glasses that are completely suitable for drivers do not squeeze the temples or bridge of the nose. You need to choose those that do not constantly slide onto the tip of the nose and do not cause irritation or discomfort. In other words, glasses should not distract attention from the road. The ideal frame is characterized by lightness. It is not wide and has narrow earhooks. There is a nose pad. The ends of the arms in this frame are made of rubber. You should pay attention to how the earhooks are attached to the frame. Compared to regular glasses, they must be fixed to the top or to the bottom. Due to this, the driver's field of vision will not be limited.

What should the lenses be like?

When choosing anti-glare glasses for drivers, you should also pay attention to the lenses. They can be made from materials such as plastic or glass. Both are capable of providing the same comfort. But glasses with plastic lenses are safer. This is due to the fact that during an accident they do not injure the eyes.

If we talk about special coatings for lenses, then modern stage there are several different options. In specialized stores, the driver can be offered anti-glare glasses or glasses with gradient tinting. You can also purchase ones that are great for driving in poor visibility. There are quite a lot of options.

The blinding of a person behind the wheel by glare from oncoming vehicles, from a wet road, from windows and windshields, from chrome and other shiny surfaces is quite common cause road accidents. Glasses for drivers have an internal anti-reflex coating that reliably protects the eyes from various glares and from excess sunlight.

Almost the same function is performed by glasses already liked by most drivers, which have gradient tinting. In them, the upper part of the lens is darkened as much as possible. It has a mirror coating. In the direction from top to bottom, the intensity of darkening decreases. It turns out that a person’s eyes are protected from bright light and glare. Through bottom part The lenses of the instrument panel are clearly visible.

Models that are necessary for driving in poor visibility

In addition, you can purchase glasses for drivers that are suitable for driving when insufficient visibility. For example, during snowfall or heavy rain. Lenses in this kind glasses are colored yellow, orange or red. They block rays of the blue-violet spectrum. Glasses of this type help to increase contrast, as well as improve color perception of surrounding components. The level of absent-mindedness and drowsiness decreases, since its causes are often visual fatigue. The lenses used in driver's glasses (yellow, orange or red) greatly help reduce glare from headlights from oncoming vehicles.

Models for visually impaired drivers

But many people have poor eyesight. Is it possible to find glasses for drivers with prescription glasses? Regardless of the fact that many glasses use simple lenses, there are also models that are suitable for people with poor eyesight. Many experts suggest purchasing glasses that are equipped optical glasses with special anti-reflective tinting. When such models are manufactured, a polarizing coating is applied to the lenses. After this they are darkened.

Additional funds

You need to purchase not only glasses for the driver (night glasses, anti-glare, gradient-tinted). Naturally, they will help reduce eye strain by protecting them from glare and bright sun rays. But they protect from the outside. Therefore, you should purchase products that will help protect your eyes from the inside. It has been found that using a substance such as lutein, it is possible to reduce the time it takes for vision to recover after being blinded by the sun's rays or the headlights of oncoming vehicles at night. Using this device can improve visual acuity and color perception. Eye fatigue will be reduced after a long period of driving.

How to find the best option?

In order to determine which glasses will be optimal for you, you should visit specialized stores or opticians. I need to try on several pairs. You can also consult with specialists. But it is worth understanding that even the most best models will not eliminate the need to be extremely careful while driving. Regardless of whether you have anti-glare glasses or anti-headlight glasses for drivers or not, you must follow the traffic rules.

What can be caused by glare?

Bright sun rays, blinding light from oncoming headlights... These factors can not only cause eye fatigue, but also lead to diseases. For example, glaucoma or cataracts. In order to protect drivers who spend most of their time behind the wheel, special glasses were created. It is worth considering what their distinctive features are.

There is an opinion that the founder of this type of glasses was Academician S.N. Fedorov. He designed relaxation-combination glasses that protect the eyes from excess light.

Which models are the most popular? Driver reviews

The Cafa France driver's polarized glasses also protect the eyes. Judging by the reviews, this is the most popular brand. They were developed specifically for drivers. They should be worn when driving in unfavorable conditions for vision: in bright sun, glare from asphalt after rains, at dusk. They will also help with blinding light from the headlights of oncoming vehicles.

Operating principle and distinctive features

Why do drivers respond so well to these models? The lenses in glasses of this kind are special light filters made of fairly high-quality plastic or mineral glass. They are coated with a thin layer of material that creates polarizing vibrations. These waves act only in the perpendicular direction of radiation. In other words, glasses are not only comfortable, but also provide high eye protection.

Ordinary light contains unpolarized waves. This is due to the fact that its atoms move freely in space. In order to change and order their structure, special linear-unidirectional polarizers are used. They contribute to the separation of radiation from ordinary light, which subsequently transmits vibrations in a certain direction.

At the interface, some of the rays are reflected. The rest are refracted. The vibrations of those rays that were reflected are mainly perpendicular to the plane on which they fall. At a certain angle of incidence, the reflected rays become linearly polarized.

Advantages

Cafa France driver glasses contribute to:

  1. Significantly improved visibility in fog, during precipitation, at dusk, etc.
  2. Reduce brightness from glare from oncoming vehicles.
  3. Reducing the degree of fatigue and drowsiness.

Anti-reflective lenses are generally labeled special sign AR. They differ from simple glasses:

  1. Complete delay of ultraviolet rays.
  2. Optimizing the intensity of those solar rays that are transmitted. The degree of clarity and contrast of the visible image increases.
  3. Good restoration of the normal state of eye tissues.

How good is the yellow lens color?

What can you say about the color of driving glasses? Yellow lenses, judging by the reviews of numerous drivers, are the most preferable. But that's not true. You should not wear this kind of model all the time. Naturally, they help improve contrast. But due to them, color and spatial sensations also change. This is especially true if windshield is not in perfectly clean condition.

Mostly yellow have anti-night glasses. For the driver it is in the dark that they are optimal, as they help brighten the image, making it clearer and more contrasty. These models are also popular among fishermen and hunters. However, they are suitable for all sports lovers.

Are glasses with different lens colors any good? Reviews from specialists and drivers

Except yellow lenses can be black, clear, brown or gray. In addition, they can be anti-reflective or night, day or with diopters. Each individual model is designed for specific conditions and vision conditions. For example, if you have visual impairments, it is better not to use polarized glasses. In such a situation, the best option is “chameleons”, which are able to adapt to the lighting.

What other nuances differ from driver glasses? Reviews from many experts say that it is best to abandon those models whose lenses have purple or blue tint. It is believed that they entail the development of lens diseases. Pink lenses contribute to headaches and nerve problems. Dark ones perfectly resist direct blinding rays, reflections from wet asphalt and glass.

Which glasses won't make your eyes get too tired?

Eyes will be less tired in glasses whose lenses have a green, gray or brown tint. But you shouldn’t use them all the time, since they also change color perception. It is best to use them in the dark or in cloudy weather, as they make the image lighter, clearer and more contrasty.

To prevent your eyes from getting too tired while driving at night, you should set the headlights to the middle position. In the event that they illuminate the wheels or trunk glass vehicle, which goes ahead, then the eyes will begin to strain more. The light beam needs to be directed slightly higher than the bumper of the car in front.

When choosing glasses, you should primarily focus on such aspects as protection, safety and comfort. In addition, they must to the fullest match the image of its owner.

Conclusion

In this review, we examined the main nuances that characterize driver's night glasses, anti-reflective glasses, and polarized glasses. We hope this will help you make a choice in favor of the optimal model.

The operating principle of polarized glasses.

Polarized glasses are designed to be worn in daytime days and are used mainly when driving a car in sunny weather.

A wave in which there is a preferred direction of oscillation is called polarization. Polarization itself is possible only in shear waves, and oscillations occur only in directions perpendicular to the direction of propagation of radiation. The operating principle of polarized glasses is based on cutting off predominantly polarized reflected radiation. When driving a car, radiation reflected from the surface of other cars, as well as from the wet surface of the roadway, is cut off. When fishing, radiation reflected from the surface of the water is cut off.

How polarized glasses with yellow lenses work

In order to understand the principle of operation of glasses with yellow lenses, it is necessary to remember the spectral characteristics of radiation sources. The color change occurs continuously and contains many halftones, so the distribution of the color spectrum is conditional.

In particular, spectral colors correspond to the following wavelengths (nm):

Radiation emitted by heated solids and liquids, has a continuous spectrum, i.e. contains all wavelengths in the visible range. The maximum is located at around 555 nm.

As can be easily seen from the graph, when using sunglasses with a transmittance of 50% (for example, polarized ones), the maximum relative visibility will simply drop to around 0.5, and when using glasses with a yellow component transmission it will remain almost at the same level. Therefore, the use of such glasses in cloudy weather and at night does not lead to significant loss of visibility.

The glow spectrum of atomic gases and vapors is a set of individual lines with characteristic wavelengths determined by the structure of the shells of the atoms of a given element. In particular, with halogen sources (car headlights), the main brightness is shifted to the blue region.

Let's move on to incandescent headlights. Radiation emitted by heated solids has a continuous spectrum, i.e. contains all wavelengths without exception, including the UV range. The characteristic color of incandescent lamps is “yellowish-white”.

Halogen headlight bulbs emit a "blue-white" color. The glow spectrum of atomic gases and vapors is a set of individual lines with characteristic wavelengths determined by the structure electron shells atoms of a given element. For example, the main spectral lines of helium atoms in the visible range are 447, 492, 587, 667, and 706 nm. Halogen lamps also have spectral lines in the UV range.

Now let's look at the yellow lenses in the glasses.

The overwhelming majority of people believe that to get yellow lenses you just need to paint transparent glass or plastic yellow. But that's not true.




Option #1. Make light filters with a narrow bandwidth (570-590 nm). In this case, they will transmit only the yellow component of light. All surrounding objects will turn yellow - some darker, others lighter. A sort of “gray-yellow movie”. It is unlikely that you can work at a computer or drive a car wearing such glasses. The color loss is simply terrible.

Option #2. Using the laws of color composition. It is known that if from white remove the blue component, it will turn yellow. Thus. If a coating is applied to glass or plastic that reflects the blue component of light, then the transmitted white radiation will turn yellow. The same thing will happen if a dye is introduced into a mass of glass or plastic, which will absorb and (or) reflect the blue component.

Protective properties of glasses with yellow lenses

1. Any filter that reduces background light improves contrast visible image and therefore improves its clarity. The main thing for the human eye is to preserve or restore (cloudy, twilight, fog) the yellow component of light, because in the daytime, the maximum spectral visibility (perception by the eye) corresponds to a wavelength of 555 nm. The main wavelength band of spectral visibility is 500-600 nm, i.e. completely includes the yellow component 570-590 nm.

2. Cloudy weather, fog, twilight. The maximum spectral visibility shifts to the blue-green region (as intended by nature!). It is necessary to deceive the human brain and eyes - change color perception to yellow - the daytime region. At the same time, judging by the spectral transmittance of coatings for glass and plastics, part of the blue-green region of the spectrum is not suppressed. Of course, there are color losses, but they are not drastic. In this case, the blue-white background light is significantly suppressed. The improvements in comfort and image sharpness are enormous - put on your glasses and all doubts will go away!

3. Night driving - yellow polarized lenses. Color perception - see point 2.

A. Incandescent lamps. Yellow lenses not only transmit, but also largely reflect the yellow component (they absorb the blue). This is the effect of protection from oncoming headlights.

B. Halogen lamps have a significant blue component of the emitted light. Yellow glass they simply filter out a significant portion of the blue component.


There are many myths among motorists, but one of them, due to its own persistence, as well as in the world latest changes in the Code of Administrative Offenses regarding the ban on tinting deserves a separate detailed discussion. This myth is that ordinary glasses with yellow lenses are suitable to protect the driver’s eyes. Like, this will be enough to prevent the sun from blinding and oncoming headlights not to glare. This misconception can harm not only your wallet and self-esteem, but also your health.

The history of driver's glasses began at the moment when the first cars became capable of reaching a monstrous speed of 12-15 kilometers per hour at that time. The approach to vehicle design and ergonomics was not particularly inventive back then, and the roads were mostly compacted earth, so it was vital for the driver to protect his own eyes from dust and dirt. As speeds increase, vision becomes the driver’s most important tool - it is necessary to clearly see the road, oncoming cars, pedestrians and everything that is happening around, so that in the event of an emergency unforeseen situation react in time and save the lives of yourself and those around you.

Even those car enthusiasts who are more or less versed in special glasses pay attention mainly to the lenses when choosing protection. Of course, this is the main part of the glasses, but don't overlook the frame. It must meet several requirements.

First of all, don't interfere peripheral vision- it is this type of vision that is responsible for the width of the viewing angle and records overtaking cars and side obstacles. How often do situations arise on the road when a driver avoids a collision only because he notices a threat out of the corner of his eye. Thus, the frame should have a narrow rim and temples. The standard adopted in Europe suggests that the width of the temples should not exceed 6 mm. In no case should the lens mount be located in the middle, blocking peripheral vision and creating a constant annoying interference. Secondly, do not create a feeling of discomfort - the frame should consist of light and durable materials so as not to lead to visual fatigue or a feeling of squeezing; you often have to spend quite a lot of time behind the wheel to minimize fatigue; every nuance is important. Finally, it is important to consider the light opening, that is, the distance from back side lenses up to the pupil. The best option is a distance of 12 millimeters - this way the field of view is not narrowed, and there are no unpleasant sensations touching eyelashes.

WITH INCREASING SPEED, VISION BECOME THE DRIVER’S MOST IMPORTANT TOOL –

YOU NEED TO CLEARLY SEE THE ROAD, ONWARD CARS, PEDESTRIANS AND EVERYTHING HAPPENING AROUND

Only after choosing a frame should you move on to lenses. And here lies the main surprise for all drivers. It turns out that there are no glasses that can provide optimal protection under any conditions and at any time of the day. The same products that are positioned as universal are not able to really protect from the sun during the day and increase contrast and clarity at night. It is worth coming to terms with the fact that if you have to drive a car in different conditions, you must have at least two different sets points.

Those who spend time driving mainly during daylight hours should opt for sun protection tinted lenses with anti-reflex coating. They reduce the intensity sunlight and protect from glare from oncoming cars, wet asphalt and shiny surfaces. As a rule, anti-glare glasses are equipped with polarization. This is quite simple to check - if you look through them at exactly the same pair of glasses, rotated at an angle of 90 degrees, their lenses will appear opaque. Branded glasses are most often equipped with a special tester - a strip with an inscription, the color of which is “cut off” by a filter, that is, the inscription becomes invisible.

Favorite by many drivers, yellow (as well as orange or red) lenses are intended mainly for driving in poor visibility conditions - in rain or fog, in the evening or at night. They cut off the blue part of the spectrum visible light, increasing color perception. There are also special transparent lenses with increased light transmittance, however, their use for a number of reasons is recommended only for people who need corrective glasses.

IT IS IMPORTANT TO BUY GLASSES IN SPECIALIZED STORES BECAUSE

THAT THEY GUARANTEE PROTECTION AGAINST UV RADIATION.

Finally, glasses with photochromic lenses, the so-called “chameleons”. However, not everything is so simple with them; it is important that they can change their transparency inside the car and have sufficient light transmission. However, progress does not stand still, and if desired, such lenses can already be found in optical stores.

It is also important to buy glasses in specialized stores because they guarantee protection against ultraviolet radiation. This is especially true for daytime glasses. According to the magazine’s expert, customer service specialist for the Point of View optical chain, Elena Aleksandrovna Tiunova, the wrong choice of glasses for driving can ultimately lead not only to emergency situations, but also cause a retinal burn: “Any sunglasses should except sun block ultraviolet radiation. Human eye designed in such a way that in the dark the pupil dilates to let in more light. When using low-quality glasses, such a dilated pupil has a catastrophic effect. large number ultraviolet radiation, if you wear them for a long time, this will lead to a terrible disease - a burn of the retina and the risk of permanently losing vision.”

The frame and the lenses themselves must be made of durable, injury-resistant material. In the event of an accident, glass lenses are highly likely to shatter into fragments, some of which are sure to injure the eye. It is better to give preference plastic lenses- they are lighter, stronger, and less likely to fog up when the temperature changes. It is also desirable that they have a special coating that protects them from scratches - not everyone has the patience to put their glasses in a case every time; many prefer to simply store them in the glove compartment or on the dashboard.

As mentioned earlier, vision is the driver’s main tool. We make sure that our car is always clean, we undergo maintenance on time and service. But even the most well-maintained and reliable car will be simply useless if the driver’s eyesight fails. So you should approach the choice of glasses with all care.
