Modern headlights, digital displays, and changing lighting conditions present new challenges for your eyes every day while driving. Bright sunlight and reflections on wet roads strain your eyes during the day. LED headlights and stray light cause glare at night—often with direct consequences for traffic safety. Recent surveys by the ADAC (the biggest german driver’s association) show that six out of ten drivers feel impaired by glare. This is a factor that can not only prolong reaction times but also increase the risk of accidents.
But how can this problem be solved? The answer lies in the combination of physiological knowledge and precise filter technology: Today’s modern eyeglasses can selectively filter out distracting light components, improve contrast perception, and thus optimize vision. However, they must not distort visual perception or unnaturally darken the surroundings.
In diesem Artikel zeigen wir, welche optischen Anforderungen Tag- und Nachtfahrten stellen – und wie Sie mit der richtigen Brillenwahl jeder Lichtsituation sicher begegnen.
Spring and summer present unique challenges: Rapid shifts between sunlight and shade—such as when driving through tunnels or encountering reflections on shiny surfaces—strain your eyes as they constantly adjust to changes in brightness.
On long car trips—such as when going on vacation—the intense sunlight can cause fatigue over the course of hours. Although high-energy visible (HEV) light (short-wavelength blue light in the 400–450 nm range) is a natural component of sunlight, we are not designed to be exposed to it for hours on end. Added to this is UV radiation, which is partly transmitted through the car’s side windows in particular.
Diese Kombination aus zu viel Licht, ständigen Wechseln und unsichtbarer UV-Belastung führt dazu, dass Ihre Augen schneller erschöpfen – besonders auf langen Strecken, wenn die Konzentration ohnehin nachlässt. Eine Brille, die gezielt diese störenden Lichtanteile filtert, ohne die Umgebung zu verdunkeln, sorgt für konstant bessere Sicht.
BluCynk is a pair of gently stimulating sunglasses that evoke the natural sensation of light from a blue sky and sunshine. With their light blue tint, they emphasize the wavelength range around 480 nm. This is precisely the range in daylight that the body perceives as a stimulating light signal. At the same time, they filter out 100% of UV radiation and reduce short-wavelength blue light (HEV, 400–450 nm), which is responsible for eye fatigue.
This combination provides a fresh, clear visual experience and reduces eye strain without compromising signal perception. Traffic lights, road signs, and the surrounding environment remain clearly visible.
This makes the BluCynk ideal for long drives in daylight when you need glasses that protect your eyes from strain without darkening your vision.
The survey results have shown that glare on the road is not a problem experienced only by a few hypersensitive individuals, but that the majority of drivers feel dazzled while driving.
The strain on your eyes becomes particularly noticeable when driving at night: Modern LED headlights emit a high proportion of short-wavelength blue light, which is scattered particularly strongly by water droplets, fog, or wet road surfaces.
Because blue light refracts more strongly, it not only causes direct glare but also makes the surroundings appear blurry and low in contrast—especially as people reach middle age and the natural clouding of the eye’s lens begins.
This is particularly unpleasant when encountering oncoming traffic or driving on wet roads. In addition, higher-mounted headlights (e.g., on SUVs) direct the light straight into your eyes, which further intensifies the glare. The result: your retina becomes overloaded, and your vision is temporarily impaired—a risk that many people underestimate.
Glasses that specifically filter out this blue light can provide greater clarity and reduced glare.
The PRiSMA DRiVE 85 is the solution to these challenges during twilight and at night. With its yellow tint, it specifically filters out blue light in the 400–500 nm range, which is responsible for the intense glare and scattering of modern LED headlights.
This improves contrast perception, making obstacles, pedestrians, and road markings stand out more clearly—without distorting color perception. The glasses are particularly effective on wet roads, in fog, or in the rain, as they reduce distracting blue light scattering.
In addition, the DRiVE 85 is also suitable for the daytime. This is especially true as we get older, when the lens of the eye naturally becomes cloudy. Targeted blue light protection can enhance contrast perception, thereby improving vision even in bright lighting conditions.
Imagine setting off on vacation completely carefree—the sun puts you in a good mood without being too bright, and by evening you arrive at your destination feeling refreshed and with relaxed eyes.
With BluCynk for daytime and DRiVE 85 for nighttime, this becomes a reality. BluCynk protects your eyes from harsh sunlight and HEV light, while DRiVE 85 ensures clear contrast and reduced glare during twilight and at night.
And the best part: With the Varia Sets, you get both in one. A frame with your prescription or, if you prefer, without lenses, combined with magnetic clip-on filters for BluCynk and DRiVE 85—so you’re ready for any lighting condition. Just put them on, hit the road, and enjoy the ride.
