Overview of frequently asked questions about blue lights
Why should blue light be reduced at all?
In the modern world, we are increasingly exposed to artificial light sources that mainly emit blue light. This blue light poses a new challenge for our bodies, as it can have negative effects on our organism.
Natural light, such as sunlight, consists of a balanced interplay of different wavelengths. The natural blue light of the sun is balanced by other wavelengths, in particular near-infrared light (dark red and near-infrared), which has cell-regenerating properties.
Unfortunately, this component of light is completely absent in LED light, which can hinder regeneration.
Since we now spend most of our lives in front of computer screens at work and end the day watching TV, using our smartphones and tablets, we should take precautions and protect ourselves with suitable blue light filter glasses.

There are software solutions such as F.lux or NightShift that can be used to reduce the blue light emitted by LED monitors. So why would you still need blue light protection glasses?
With software solutions such as NightShift or Flux, the blue component can only be eliminated with settings that lead to a significant change in color reproduction and image blurring. Blue light protection glasses eliminate the blue components much more effectively and still offer better color reproduction.
A 2017 study by the Lighting Research Center, Rensselaer Polytechnic Institute, Troy, USA, confirms that melatonin suppression is not significantly prevented by a software solution.

Can I wear blue light protection glasses while driving?
Due to their special filter characteristics, which affect signal light suitability, the PRO99 and LiTE95 filters are not recommended for use in road traffic. The EASY90 “gamer” filter, on the other hand, can be used during the day. For optimal vision while driving, we have developed the DRiVE85 filter, which offers outstanding properties for high-contrast and glare-free vision, especially when driving at night.

Why are PRiSMA BluelightProtect lenses so heavily tinted? There are blue light filter glasses that are colorless, which is much more comfortable for the eyes…
Colorless eyeglass lenses can only reduce blue light to a very limited extent. According to the physical laws of optics, if a lens does not look yellow, it can hardly filter blue light. Likewise, not every yellowish lens filters blue light sufficiently, especially not the parts that are particularly harmful to the eye and retina!
PRiSMA BluelightProtect filter lenses are strong and highly precise filter lenses with outstanding blue light filter values.

Why does the blue light have to be filtered out to such a high degree? Wouldn't it be sufficient to filter out 30 or 50 percent, for example? Wouldn't that result in less impairment of color reproduction?
Our aim is to offer blue light protection that is worthy of the name and takes all relevant aspects into account.
It is important to note that the blue component of LED light must be assessed differently than that of sunlight.
Sunlight does not lack red and infrared (NIR) components, as is the case with almost all modern artificial light sources. This long-wave NIR has cell-regenerating properties that counteract the cell-damaging blue component because they can promote regeneration.
Therefore, glasses with blue light protection that usually does not even reach 450 nm are far from effective enough, as a high proportion of blue light can still pass through and penetrate the eye's retina.
We therefore recommend glasses with strong blue filters. Our range includes protection levels from 90 to >99% as well as another with special features for driving.
Alle Filter sind so maximiert, dass die Farbwiedergabe so hoch ist, wie dies technisch möglich ist.
Wir möchten darauf hinweisen, dass es möglicherweise nicht ratsam ist, sich uneingeschränkt auf die Angaben zu Blaulichtfilterwerten bei bestimmten Arten von verfügbaren Brillen zu verlassen. Oft beziehen sich diese Angaben lediglich auf Teilbereiche des Blauspektrums, das einen Bereich von 400 bis 500 nm abdeckt.

Can BluelightProtect filter glasses also be used as sunglasses?
All filter lenses offer 100 percent UV protection, which means they can be used without hesitation in natural light.

But blue light is only dangerous in bright light…
It is true that effectiveness and danger depend in part on light intensity.
However, what is often ignored in such statements is the eye's adaptation to lighting conditions. In dim light, not only do the pupils dilate to let in more light, but larger amounts of the visual pigment rhodopsin are also produced, which increases the activity of the photoreceptors. This means that even less intense light can have a strong biological effect.
A strong blue-emitting LED in addition to bright daylight is therefore far less serious than exclusively blue-emitting, albeit dim, lighting.
When working at a computer screen in particular, it should also be noted that although LED light is not particularly intense in itself, it can be seen directly from a short distance, often for hours on end.
Setting the monitor to a darker setting is often not a solution either. On the contrary, since many flat-screen monitors regulate brightness using pulse width modulation, this only means that the light (at the same intensity) is switched on and off. The darker the monitor is set, the longer the dark phases between the light pulses.
The resulting imperceptible flickering is another stress factor for the eyes.
