Many people today like to drive a car.However, the midday sun, blinding motorists can be a real challenge for people who are behind the wheel.Roofs are not always able to help.This makes the process of driving the vehicle more difficult.What to do in such a situation?
There comes the warm summer days, and more and more drivers are beginning to use glasses for the car to protect your eyes from the direct rays of the bright sun while driving.
Glasses antifary
Many avid driver asked: "Why should I, in fact, special car glasses, if I already have a super-mega-cool and expensive sunglasses?"The answer is simple: security.
Sunglasses for car able to reflect the glare from the surface of the wet asphalt, windshields, as well as the sun's rays, and more.This is possible because of the polarization filter.
Points road there are all sorts of colors, shapes, sizes, and are made of various materials.Moreover, the materials are not only plastic and metal, and nylon.
Glasses antifary whose price is not much more conventional sunscreens (lower limit - 250 rubles), made of nylon, particularly valued for what they have hypoallergenic properties.Or, simply put, using points, which material - nylon, the skin around the eyes is not a hint of irritation.If the car owner often makes long trips, the glasses antifary nylon have a huge advantage over glasses of a different material.
main function accessory - eye protection is the owner of headlights coming towards cars.In addition, night glasses antifary must be absolutely safe for the health of the driver's eye transport.However, this quality can boast not every model presented for sale.That is, the points may be the road you come in as normal glasses to protect your eyes from the sun, but as the road they can be dangerous and even cause an accident.For example, because of the wide rim, you can not help noticing the pedestrian.
Driving on night road has its pluses and minuses
Of the benefits can be called that road at night more free, so the driver has a better chance to enjoy driving.However, the drawback of the night riding enough.For example, poor visibility, blinding headlights of passing cars.Especially hard to have when not too smart drivers forgetting to switch the light on a distant neighbor.
Undoubtedly, everyone wants to look stylish and beautiful.However, when it comes to safety, it is wiser to ignore these factors.In the event of an emergency on the road is released airbag inflation and then it hit her about the one who is behind the wheel.If glasses antifary for drivers are unsuitable or of poor quality, the additional trauma can lead to vision loss or even worse, death.
Often in such cases, glasses are broken lenses or broken frame with bows.Consequently, one of the conditions for the correct production of glasses to lenses have been made of plastic, and in any case is not made of glass.When you hit the glass broken, and multiple small fragments can get into the eyes and damage them.Risk injure eyes with lenses made of plastic at times less.Also glasses antifary should have a narrow rim.It will not obstruct the driver's view, and he will not have to turn more and more on the side of the head.
The human eye is designed so that the angle of its review of the order of one hundred and twenty degrees.Ninety of them we see clearly - the so-called central vision.The rest falls on the peripheral region.
However, when driving at a speed of about one hundred kilometers per hour central vision narrowed significantly - up to forty degrees.Therefore, at the periphery have much greater significance.If glasses antifary have a wide rim, in order to, for example, look in the mirror, you need more to turn his head, that is, aside from the road.Why is that?Because wide shackle prevents glance that can create an emergency situation on the road.
We have already given a hint about what material should be made of the lens to be considered safe.Suppression bright glare, which arise from sunlight and car headlights included - another important property of the lens.Polarizing glasses for drivers to have this property.These lenses have a polarizing filter to extinguish the light is too bright.
How do you know that has a lens filter or not?
Very simple!To do this, you need to look at the screen of an electronic device, such as a phone or a tablet.Then slowly rotate the glasses antifary night for the driver to ninety degrees.The filter at the lens is, if it has darkened.
experimentally proved that the glasses antifary have greater reflectivity.Thus, placing ordinary road and points into the spectrometer, then the reflectance of the transparent lenses is less than ten, whereas the road it will twice more.
That is what will allow your eyes to adjust when a car that is moving towards you at a distance of two or three hundred meters, you dazzle.However, if the distance is less than the machine, you will not save even the glasses: the eyes do not have time to adapt.
Another important property of the lens - is the light transmittance.International Standard ISO states that the polarizing glasses for drivers should have an indicator light transmission of at least seventy-five percent.That's how much visible light they need to pass.
If this value is less than the lens, then poor visibility at dusk driver provided.It's no secret that it can cause an emergency.
course, every driver has a right to choose glasses that he wear.However, in terms of driving safety it may be better not to take the most beautiful, but security.
What are the main functions of points for drivers?
First, it increased the clarity of the image.Second, the points for the drivers needed to improve the visual response.Thirdly, they should increase the perception of spatial depth.
Glasses antifary, reviews which are mostly positive, are designed to expand the review of the track when the driver operates the vehicle.Thanks to them, the one who drives the car, will not feel any discomfort while traveling in bad weather, as the vast majority of accidents occur due to the fact that the driver failed to notice the impending danger.
Yellow glasses for drivers (found in the sale and orange) can be used on cloudy days and during the warmer days.They improve clarity, color discrimination and contrast.Yellow glasses for drivers have one major drawback: while driving the driver will always have to turn his head.This contributes to fatigue of the neck and eyes.
Now understand, what properties should have antifary glasses for driving.What are their differences from ordinary sunglasses accessories?
Color
best to protect from sunlight sunglasses with gray and brown color filters, while the red, orange and yellow are perfect for twilight and night driving.Interestingly, some models of glasses-antifar are the ability to change lenses, but it is very rare.
Polarization eyeglass lenses
these glasses are polarizing coating, which ensures reliable protection against the negative effects of radiation.Polarized lenses are protecting eyes from the blinding headlights from sunlight and various shiny surfaces such as snow, water, wet road and so on.
Check whether there is a coating, it is simple enough.It is necessary to put on the glasses and look through them to other points with similar lenses.Next you need to turn your head ninety degrees - coated glasses will seem dark.You can also look at the screen of an electronic device.
gradient coating
gradient coating - a necessary condition for good road points.It is a lens on the top of which a mirror coating, and the lower part transparent.Gradient coating allows the driver of the vehicle clearly observe the dashboard and at the same time protect from the sun's rays that fall from above.
coating that protects from scratches
During the selection of glasses for driving you must ask the seller whether there is a special coating on the lens.If he says that there is, try a little scratches.If even such an impact on the lens are traces, it is best not to take this model, because for a long time, it is hardly enough.
Light transmission
This test is very important for automotive glasses.The indicator light transmittance must be at least seventy-five percent.If it is lower, then you will see worse at dusk and during the night traffic.
Comfort
If you are uncomfortable in a car with glasses, then they will be of little use.When you select points to be preferred model with a narrow rim.Broad will bring you a lot of inconvenience: they are much close review, especially when you are driving at high speed.Points for driving should sit tight on the head of the driver.In no case do not have to choose a model that slides from the head.
not harm vision
There are special vision glasses that are designed for people with visual impairment.It is interesting that in any store model with diopters are sold on a par with conventional driver's points.
If you are still in doubt about whether you need glasses for driving, we can safely say that they greatly facilitate your life.A well-chosen accessories and quality will improve your visual response, improved clarity of images, increase the depth of spatial perception.And while they will be absolutely comfortable.
