Sunglasses when Driving a Car
Sunglasses can significantly increase driving safety not only in summer, but also in other seasons. Especially in the evening and morning hours, some drivers have great difficulty blinking against the low sun. Thanks to the best sunglasses for driving, there is a safer view.
However, not every pair of glasses has this desirable effect. The intensity and color of the tint are particularly important :
- The tint of a car-compatible sunglasses may be a maximum of 82 to 92 percent (better even only 75 percent). That corresponds to glasses category three. With a stronger tint, many objects and danger areas simply look too dark.
- The tint colors yellow and green are quite suitable, since they hardly distort the signal colors red and money, which are important in road traffic. Blue sunglasses, on the other hand, have the disadvantage that they noticeably weaken the traffic lights and car brake lights, for example.
- An integrated UV and blue light filter protects the retina and optic nerve and should therefore be a matter of course.
Polarizing glasses are also recommended as they prevent annoying reflections. So-called gradient lenses, which have a stronger darkening in the upper area than below, are also useful. On the other hand, the self-tinting glasses largely fail to serve their purpose: the tinting reacts very slowly to fluctuations in brightness (or even not at all if the triggering UV light is filtered out through the car windows).
It is also important that the sunglasses are particularly light for long driving and do not interfere after several hours. Eyeglass wearers with poor eyesight naturally need sunglasses with the right prescription.
Sunglasses at night?
Strongly tinted sunglasses at night are completely unsuitable and even prohibited. The yellow night driver glasses , which are supposed to intensify the nightly contrasts, may filter a maximum of 25 percent of the incident light. Who wears stronger sunglasses in night traffic is not "cool", but simply recognizes too little and endangers himself and other road users.
Not All Sunglasses are Suitable for Driving
In summer, high temperatures can strain the driver's nerves and the bright light and reflections can blind the driver. The consequences are often a more aggressive driving style and an increased risk of accidents. If you are traveling by car, you should set the air conditioning to around 21 to 23 degrees and have sunglasses at hand at all times. But not all sunglasses are suitable for driving.
Good sunglasses are basically the most effective protection against bright light. But drivers should pay attention to the color of the glasses and the tint. If the glasses are red, blue or orange, for example, they should not be used in road traffic because they could falsify the colors of street signs and traffic lights. Also, the sunglasses must not be too tinted. The so-called anti-reflective lens category provides information about this. Up to level 3, the glasses let enough light through, but from category 4 onwards, drivers should refrain from doing so. Because those who barely see the street are negligent. Information on the translucency is on the inside of the bracket, the imprint «Cat. 3 »corresponds, for example, to glare protection category 3.
If you want to protect yourself from glare, you should also think about polarized glasses. Glasses with an integrated polarization filter usually cost an extra charge, but they can minimize reflections, such as those that occur on wet roads. Sunglasses with polarizing filters are suitable all year round, for example also well in winter, since they can also effectively absorb reflections from snow or ice. Gradients are also often more expensive. But they have one advantage: Drivers can easily see the speedometer nearby and the road in the distance.
If you wear glasses anyway, you should also consider tinted topcoats. The enlarged frame of the sunglasses is pushed over the frame of the regular visual aid. The following applies to all glasses: frame and temple should be as narrow as possible so that the field of vision is not restricted.
