Glasses for the driver is not a whim at all, nor any kind of "show off". This is a very necessary and important accessory that helps ensure the safety of both the driver and his passengers. Only glasses with polarization, in other words, capable of eliminating reflected light, are called professional driver's glasses.
They protect eyesight from the headlights, eliminate excess ultraviolet light, and in any weather they will be simply irreplaceable.
There are several simple rules for selecting driver points:
- Driving glasses should preferably be gray or brown. They reduce glare, and do not change the perception of color;
- Do not take too dark lenses, as well as amber or yellow lenses;
- To avoid damage in case of possible accidents, choose polycarbonate lenses;
- try to choose lenses that protect against ultraviolet radiation;
- Use lenses with proper casting. Otherwise, distorted reflections will cause headaches.
In which cases the driver needs glasses
Summer days, with their abundance of heat, bring a lot of joy, but at the same time they bring a lot of trouble and discomfort to drivers. From noon to four, the sun shines especially brightly. During these hours it is better to move in a car with safety glasses. In addition, at this time, ultraviolet rays, which are especially harmful, are intensely showing themselves.
In the early morning hours, and also in the evening, the sun does not manifest itself so negatively. But this does not mean at all that its rays will not cause trouble. Moreover, at this time they are directed directly into the eyes. Light falls on the face of the driver with a slope of 45 degrees and naturally the person begins to squint instinctively, which reduces visibility.
If the car driver does not use protective optics, then he can see the obstacle that has arisen on the road only five meters from him, and this is sometimes very small for the car to stop when braking.
Many car owners purchase special sun visors. But they do not always help out. An example of this is ordinary rain, after which there are puddles on the track. Light reflected from the surface of the water will create glare. And here the visor will be powerless. Naturally, sunlight is not among the dangerous factors leading to an accident, but the wet surface of the asphalt is like a mirror and no visors and tinted stripes can eliminate this negative factor.
Important! No less danger comes from the windows of cars that go in the opposite direction. Getting on them, the light, as a rule, is reflected directly into the eyes of the driver.
For some time, the driver may lose the ability to see normally after he drove through an unlit tunnel or drove out of a parking lot where there was little light. In this situation, it is recommended to pull over and wait until vision is normal.
It is worth saying that driver’s glasses should be coated against ultraviolet rays, which adversely affect the eyes. This radiation causes burns to the retina, which can lead to big problems with vision.
Types of driving glasses
Sun protection
They are most common in a driving environment. However, they do not protect against glare, and in addition, they have low bandwidth (no more than 18-4З%). There are several color solutions on sale:
- Gray color. This shade is very popular and widespread. Equally suitable for both men and women. It does not change the color of sunlight, but only makes it a little duller, reducing brightness and reducing the amount of glare.
- Orange, yellow. Lenses of this color are suitable for driving in foggy conditions. In winter, they distort color reproduction.
- Brown, canary color. On cloudy days, they improve the quality of vision.
- Ruby, pink color. Such lenses cut off the waves of light in the blue spectrum, the eyes in them do not get tired and do not overwork, even if they are used for a long time.
Polarized coating
Their main advantage is their additional ability. In addition to eliminating glare from the sun, they help protect the eyes from the glare that the sun creates in the eyes and reduce light saturation.
True, in all their glory, they show themselves only when there is good lighting. If there is night or twilight outside, they limit visibility, and in bad weather their effectiveness is zero.
Photochromic coated
If you wear glasses all the time, it will be nice to use optics with a photochromic coating. Under the influence of sunlight, they darken. These glasses are also called "chameleons." In low light conditions they brighten. Indoors they cannot be distinguished from classic corrective ones. In the recent past, it was impossible to use “chameleons” in a car, since ultraviolet rays do not pass there, but glare from freely penetrate. But the ophthalmological industry is constantly moving forward and these days they can be used inside the car salon.
With diopters
This type of glasses is prescribed to car owners with visual impairment. By purchasing them, it will be more productive to opt for lenses that have an anti-reflective coating, which nullifies various reflections.
Headlights
In the manufacture of this type of protective device, plastic, various polymers or glass lenses are used. They perfectly protect from the light of the sun, and from various types of glare. It will be comfortable with them even in low light. They cost a little more than simple sunscreens. But for those who drive the car most of the time, they will be very useful:
- Their main advantage is excellent protection from the light of oncoming headlights;
- they do not damage eyesight. But this is not true for all points that are on sale;
- they have a high reflectivity;
- they do not interfere with the passage of light. Even if there is not enough light around, then this will not be an obstacle for the driver with them.
Rules for choosing a driver's glasses
Polarized plastic
The first step in choosing glasses is the material. However, the choice is small and unambiguous. Glass lenses are not suitable for driving. It is better not to bother with thoughts of accidents, but in any case, the glass breaks into many small parts during the impact. Naturally, eye injury cannot be avoided. Plastic lenses, although more expensive, are safer. It is difficult to destroy them into many pieces, which means that the risk is reduced to a minimum level. But there is also a minus. Glass is more durable and does not get scratched.
The arms of the optics should be as narrow as possible, this is true for the frame itself. The greater the thickness, the smaller the field of view. At high speeds, this field is already shrinking, and such a design of glasses can do even more harm.
The main thing you should pay attention to are lenses. Sun protection from all the inconveniences will not help. Although they hold up a lot of excess light, they do not eliminate all glare, reflections and the light of oncoming headlights. It is better to take lenses with a polarized coating.
They are part of the screening of all waves in horizontal directions.
"Antifarah" and photochrome
If visibility is poor, a completely different kind of optics should be used. Usually on store shelves it has the name "antifare". They have red, yellow or orange colors, and in the lower part they have a mirror strip.
When using them, the image becomes contrasted, the colors are clearly different.
In addition, you can often find optics that change the level of transparency of the glass, depending on external lighting. These are photochromic coated lenses. But often they can not be very useful, and sometimes even harm, because the time for changing transparency can reach fifteen minutes.
