So many people today love to drive a car. However, the midday sun, blinding motorists, can be a real test for people driving. Visors are not always able to help. This makes the process of driving a vehicle more difficult. What to do in a similar situation?
The warm summer days are approaching, and more and more drivers are starting to use glasses for the car in order to protect their eyes from the direct rays of the bright sun while driving.
Antifog glasses
Many avid drivers will ask: "Why do I actually need special car glasses if I already have super-mega-cool and expensive sunglasses?" The answer is simple: for security.
Sunglasses for a car can reflect glare from the surface of wet asphalt, windshields, as well as the rays of the sun and more. This is possible due to the presence of a polarizing filter.
Car glasses exist in all kinds of colors, shapes, sizes, and are also made from a variety of materials. Moreover, the materials include not only plastic and metal, but also nylon.
Antifog glasses, the price of which is not much higher than conventional sunscreens (the lower limit is 250 rubles), made of nylon, are especially appreciated for the fact that they have hypoallergenic properties. Or, in simple terms, when using glasses, the material of which is nylon, there will not be a hint of irritation on the skin around the eyes. If the car owner often makes long trips, then nylon anti-headlight glasses have a huge advantage over glasses made of other material.
The main function of the accessory is to protect the wearer's eyes from the headlights of cars coming towards them. In addition, night glasses-antifarads must be absolutely safe for the health of the eyes of the driver of the vehicle. However, not every model on sale can boast of this quality. That is, automobile glasses may well suit you as ordinary glasses to protect your eyes from sunlight, but as a road glasses, they can be dangerous and even cause an accident. For example, because of the wide rim, you may not notice a pedestrian.
Riding on night roads has its pros and cons
One of the advantages is that the road at night is freer, so the driver has more chances to enjoy driving. However, there are enough minuses for night driving. For example, poor visibility, blinding headlights of passing cars. It is especially difficult when not too smart drivers forget to switch the high beam to the low beam.
Undoubtedly, every person wants to look stylish and beautiful. However, when it comes to security, it would be wiser to neglect these factors. In the event of an emergency on the road, the airbag is released, then it is inflated and hit by someone who is driving. If driver antifog glasses are unsuitable or of poor quality, additional injuries can lead to loss of vision or, even worse, death.
Often in such cases, the lenses are broken at the glasses or the frame with the arches breaks. As a result of this, one of the conditions for correctly made glasses is that the lenses are made of plastic, and in no case made of glass. With a strong impact, the glass will break, and multiple small fragments can get into the eyes and damage them. The risk of injuring the eye with plastic lenses is several times less. Also, anti-headlight glasses should have a narrow frame. She will not obscure the driver’s vision, and he will not have to turn his head more and more frequently.
The human eye is designed so that its viewing angle is about one hundred and twenty degrees. Ninety of them we see clearly - this is the so-called central vision. Everything else is in the peripheral area.
However, when driving at a speed of about a hundred kilometers per hour, central vision is significantly narrowed - up to forty degrees. Therefore, the periphery is much more important. If anti-headlight glasses have a wide frame, then, for example, to look in the mirror, you need to turn your head more strongly, that is, distract from the road. Why? Because a wide bow makes it difficult to cast a glance, which can create an emergency on the road.
We have already hinted at what material lenses should be made of in order to be considered safe. The suppression of bright glare that occurs from sunlight and the included headlights of cars is another important property of lenses. Polarized glasses for drivers have this property. Their lenses have a polarizing filter to damp out too bright a light.
How can I find out if a lens has this filter or not?
Very simple! To do this, you need to look at the screen of an electronic device, such as a phone or tablet. Then slowly turn the night glasses for the driver ninety degrees. The lens has a filter if it has darkened.
It has been experimentally proven that anti-headlight glasses have a high reflection coefficient. So, if you put ordinary and automobile glasses in the spectrometer, then for transparent lenses the reflection coefficient will be less than ten, whereas for automobile lenses it will be twice as much.
That is what will allow your eyes to adapt if a car that moves towards you at a distance of the order of two hundred or three hundred meters blinds you. However, if the distance to the car is less than indicated, then even glasses will not save you: your eyes will not have time to adjust.
Another important property of lenses is light transmission. The ISO international standard states that polarized glasses for drivers must have a light transmittance of at least seventy-five percent. That is how much visible light they must pass.
If the value of this lens parameter is less, then poor visibility at dusk is provided to the driver. It's no secret that this can cause an emergency.
Of course, each driver has the right to independently choose the glasses that he should wear. However, from the point of view of driving safety, it may be better for him not to take the most beautiful, but the safest.
What are the main features of glasses for drivers?
Firstly, it is an increased image clarity. Secondly, goggles for drivers are needed to improve visual response. Thirdly, they should increase the depth of spatial perception.
Antifog glasses, reviews of which are mostly positive, are designed to broaden the view of the track when the driver is driving a vehicle. Thanks to them, the one who drives the car will not feel any discomfort when traveling in bad weather, since the vast majority of emergency situations occur due to the fact that the driver was not able to notice the impending danger in time.
Yellow glasses for drivers (found on sale and orange) can be used in cloudy weather and in the warm time of the day. They increase image clarity, color discrimination and contrast. Yellow glasses for drivers have one significant drawback: while driving, the driver will have to constantly turn his head. And this contributes to the rapid fatigability of the neck and eyes.
Now we will figure out what properties anti-headlight glasses should have for driving. What are their differences from conventional sunscreens?
Color
Glasses with gray and brown filters are the best protection against sunlight, while red, orange and yellow are great for twilight and night driving. It is interesting that some models of antifar glasses provide the ability to change lenses, but this is very rare.
Glasses lens polarization
The lenses of such glasses are polarized sprayed, which guarantees reliable protection against the negative effects of radiation. Polarizing lenses protect your eyes from blinding headlights, from sunlight and various shiny surfaces such as snow, water, wet roads and more.
Check if there is such a spray is quite simple. It is necessary to put on glasses and look through them at other glasses with similar lenses. Next, you need to turn your head ninety degrees - the sprayed glasses will seem dark to you. You can also look at the screen of an electronic device.
Gradient coating
Gradient coverage is a prerequisite for good car glasses. It is a lens, on the upper part of which is a mirror coating, and the lower part is transparent. The gradient coating allows the driver of the vehicle to clearly view the dashboard and at the same time protect it from the rays of the sun that fall from above.
Scratch resistant coating
When choosing glasses for driving, you must ask the seller if there is a special coating on the lenses. If he answers what is available, then try to slightly scratch their surface. Even if traces remain on the lens from such an impact, it is better not to take this model, since it is unlikely to last for a long time.
Light transmission
This criterion is extremely important for automobile glasses. The light transmission must be at least seventy-five percent. If it is lower, then you will be worse at dusk and during night traffic.
Comfort
If you are uncomfortable with automobile glasses, then they will be of little use. When choosing glasses should give preference to models with a narrow frame. Wide will give you a lot of inconvenience: they will greatly obscure the view, especially when you are traveling at high speed. Driving glasses should fit snugly on the driver’s head. In no case should you choose a model that slides from your head.
Do not harm eyesight
There are special glasses with diopters that are designed for people with visual impairment. It is interesting that in any store models with diopters are sold on a par with ordinary driver's glasses.
If you still doubt whether you need glasses for driving, then we can safely say that they make your life much easier. Properly selected and high-quality accessories will improve your visual response, increase image clarity, and increase the depth of spatial perception. And at the same time they will be absolutely comfortable.
To date, car glasses are especially popular among drivers of vehicles. With their help while driving you will feel protected from the weather and other adverse factors. You no longer have to look closely at the road. In front of you you will see a clear picture of everything that is happening and at any time you will be able to react to an unexpected traffic situation.
It’s good if you get some high-quality polarizing glasses for drivers. Some should be used on sunny days during the daytime, while others should be used for twilight, that is, for night trips.
