Are all Blueblocker glasses coloured yellow?

Are all Blueblocker glasses coloured yellow?

The answer is clearly no. It would also be better to ask the question "Why are some blueblocker glasses coloured yellow?" and "Do all yellow lenses also block blue light?"

The colouring of the lenses does not say much about the filter quality. A good example are ski goggles with yellow tinting. This is supposed to increase contrast and make bumps on the slope more visible in bad weather. Measurements will show that parts of the blue spectrum still come through.

However, one can generally say that the darker the colouring of the lenses (light yellow-yellow-orange-red), i.e. the "redder" the glasses, the more blue light, or rather, the more wavelengths in the visible spectrum are blocked. Therefore, with dark orange and red colouring, green light is also filtered.

What you can deduce from this, for example, is that transparent lenses can only block a small part of the blue light, light yellow ones probably filter out more than transparent ones and orange ones a little more, and so on.

So when do you use which tint now? I'll show you a few possible applications here:

Clear glasses

There is a wide range of clear glasses marketed as blueblockers.

As I said, these lenses can only filter out a small part. So if you see advertising claims that the filtering power of these lenses is higher than 5-30%, you should be sceptical. These glasses are usually found under the heading "computer glasses". They are supposed to protect against dry and strained eyes.


Blue light filter

100% blue light filter performance

max. 30%

Sleep (protection from melatonin suppression)
Stress reduction for the eye (protection of sensitive photoreceptors)

I personally don't think much of wearing glasses during the day, especially when I don't need glasses anyway. It's important to get the full spectrum of light throughout the day, into the eyes and, at best, onto the skin.
For computer work during the day, it makes sense to think about a filter like f.lux or Iris to achieve a similar effect.

However, if your work environment is plastered with bright LEDs and screens and you have difficulty getting natural light into your workspace, such glasses may be the right solution.

Yellow glasses

Yellow lenses can already block far more blue light. Since we mainly focus on the time when the sun has already set, you can use these glasses for yourself as driver's glasses in road traffic. While the darker versions, which we will come to, are not permitted in road traffic, this is possible with yellow lenses (always make sure that you are actually approved for this). Especially the LED and xenon headlights are a potential problem on the way home, where you actually want to go straight to sleep.

So if you're on the go a lot and still want to be consistent, the yellow glasses are a good choice.

Orange glasses

Orange Blueblocker Glasses

These glasses are supposed to provide better sleep. As long as the Blueblocker glasses are of good quality, they can already filter out 100% of the blue light spectrum.

This makes sense because in the historical context, once the sun had set, we no longer had light available. Unless we built a fire. We are very well used to that.

If you look at what kind of light spectrum fire provides, you will see that blue light is hardly if at all represented. This is a simple explanation to understand why we want to filter this very part of the light to better prepare the body for sleep.

Since we "turn night into day" with modern lighting and screens, our inner clock does not have the opportunity to set itself correctly and thus to correctly dose the hormone release, especially of the sleep hormone melatonin, which is also called the "dark hormone".

So orange glasses help us to better establish the natural context after sunset, in an artificial environment, so that our body gets into a better rhythm and we sleep more deeply.

Dark orange/red lenses

Red blue blocker glasses

These glasses block another part of the light spectrum, they reach into the green spectrum. With these lenses, you reportedly get tired even faster. Otherwise, just like the orange lenses, they serve to prevent our night from turning into day, but you no longer have such good colour rendering.

Conclusion - Are all Blueblocker glasses coloured yellow?

No, as we now know very well after the article.

The tint and the quality of the lenses play a role in the right choice of a Blueblocker Glasses. In addition, there is the desired area of use and personal preferences.

The important thing about quality is that it really filters what the manufacturer promises.

During the day, you should avoid filtering certain wavelengths, unless you are in a completely artificial environment and nothing can be done about that quickly. If that's not the case, I'd use a software-based filter like Iris or f.lux during the day to provide plenty of natural light. However, if you are very sensitive to light and feel that your eyes are overstrained, give it a try.

As a small tip - try to always look through the window into the distance and give your eyes a little break from the display.

If you spend a lot of time cycling or driving in the evening, the yellow glasses are quite recommendable, as long as the glasses are approved for road traffic.

Otherwise, to protect you from blue light in the evening and prepare your body for the coming sleep, orange or orange-red glasses are the right choice. Especially if you are still sitting in front of the TV, tablet, mobile phone, notebook or computer.

Whether orange or red-orange is the right choice for you depends more on personal preference. We recommend combining the two versions, depending on what you have planned for the evening, you can then choose one or the other.

As a small tip - create a "campfire setting" in the evening by additionally working a lot with candlelight and relaxed, not too bright light sources.
