Blue-light glasses usage advice
How to get the most out of your blue-light glasses
The Alina glasses are designed to be integrated into daily life in a simple and effective way. Not by completely avoiding blue light, but by allowing the right type of light at the right time through. In this guide, we explain how to use the Alina day glasses and night glasses optimally, in line with the body's natural day-night rhythm.
Light, timing, and the circadian rhythm
The human body responds strongly to light. During the day, light helps us stay alert and focused. In the evening, light tells the body whether it is still “daytime” or whether it is time to relax and produce melatonin. Artificial light and screens can disrupt this natural process.
The effectiveness of blue-light glasses therefore depends not only on what is filtered, but especially on when the glasses are worn.
Alina Day Glasses
The Alina day glasses are intended for use during the day, especially during prolonged screen use. Our rule of thumb: Wear the glasses indoors only when exposed to a lot of artificial light, screens, and laptops.
When to wear:
-
During prolonged use of a computer, laptop, or tablet
-
In environments with a lot of artificial light (offices, schools)
Purpose:
-
Reducing digital eye strain
-
Greater visual comfort throughout the day
-
Supporting sustained concentration
The day glasses filter some of the high-energy blue light without completely removing the feeling of natural daylight. This allows the body to understand that it is still “daytime,” while reducing strain on the eyes and circadian rhythm.
Alina Evening Glasses
The Alina night glasses (red evening glasses) are designed to fully block blue light. Rule of thumb: When it is dark outside, put on the Alina red evening glasses.
This is the simplest and most natural guideline, because it allows the body to truly follow the rhythm of the sun. In winter, it is often still dark when you wake up in the morning. In that case too, wear the glasses until it is light outside.
Seasonal adjustment
Because it gets dark early in winter, this rule of thumb can sometimes feel impractical. In that case, we recommend:
-
Winter:
Wear the day glasses until after dinner, then switch to the red night glasses. -
Summer:
Even if it is still light outside, put on the night glasses 1 to 2 hours before bedtime. In the morning, it is often already light when you wake up, so the glasses are not necessary then.
This way, the body still receives the signal that the day is coming to an end, regardless of the amount of outdoor light.
Important considerations
We strongly advise against wearing the red night glasses while driving or in other situations where optimal vision is essential. The red lenses can limit visibility and color perception, which may be unsafe in traffic.
Many people have been accustomed to exposure to blue light in the evening for years. When this is suddenly greatly reduced, the body may initially react to it.
Possible reactions:
-
Fatigue
-
A “heavy” feeling in the head
-
In some cases, mild headaches
This does not necessarily mean that the glasses are unsuitable, but that the body needs time to adjust.
Our advice if you are sensitive:
-
Start with 30 minutes before bedtime
-
Gradually extend this over several days
-
Listen to your body and do not force anything
Medical conditions
Do you have an eye condition, neurological symptoms or other medical concerns? Always consult your doctor or specialist first before making changes to your light exposure.
Consistent use for long-term results
The effectiveness of light management does not come from one-time use, but from consistency. By wearing the day glasses consistently during the day and the night glasses consistently in the evening, you create a clear, repeatable signal for the body. It is not for nothing that the word biorhythm contains the word ‘rhythm’.
Extra tip: combine light strategies (Yin & Yang)
For the best results, we recommend combining three elements:
-
Plenty of daylight during the day
Go outside regularly, especially in the morning. Daylight tells the body that it is daytime. -
The Alina night glasses in the evening
This signals to the body that the day is coming to an end. -
Red light in the evening
Red light contains no blue light and has no flickering, unlike many regular lamps. Even when wearing night glasses, flickering from standard lighting can still be taxing.
If you wear glasses in the evening but do not use red light, you may still experience discomfort from light flickering. You can read more about this in our separate blog about flickering, where we explore this topic in greater depth.
This balance between daylight and the absence of blue light in the evening creates a natural “yin and yang.”
