Which LED color is good for the eyes or even helps against headaches?
4 min Time to read
In this day and age, we are surrounded by LED lighting, whether at home, in the office or on the go. While LEDs are energy efficient and long-lasting, the question arises as to which light colors are best for our eyes and whether certain colors can even help relieve headaches.
Which LED color is good for the eyes - and can even help with headaches?
LEDs have become an integral part of our everyday lives. Whether at work, in the living room or even outdoors - modern LED lights bring brightness, efficiency and style into our lives. However, not every LED is automatically pleasant for our eyes. Especially with For longer periods indoors, when working at a computer screen or for light-sensitive people, the question arises: Which LED color is particularly easy on the eyes - or can even help against headaches?
We at Skapetze take a detailed look at the effect of light colors on the body and give tips on choosing the right LED lighting for greater well-being.
Light color and its effect - why Kelvin is more than just a number
The so-called color temperature of an LED is measured in Kelvin (K). Depending on the Kelvin value, a rough distinction is made between
Warm white (below 3300 K) - cozy, calming, ideal for living rooms
Neutral white (3300-5300 K) - matter-of-fact, clear, good for work areas
Daylight white (over 5300 K) - activating, cool, often used in offices and workshops
This distinction is not just a question of aesthetics - it also has a direct effect on our visual health and well-being. Warm light colors, which resemble natural light at sunrise or sunset, are particularly pleasant to the eye.
Cold light, on the other hand, contains more of the blue spectrum, which can damage the eyes with prolonged exposure.
Blue light: a curse or a blessing?
A decisive factor when it comes to LEDs and eye strain is the proportion of blue light. Cool white LEDs emit a higher proportion of blue light.
Although this ensures alertness and concentration, too much of it, especially in the evening, can disrupt the sleep-wake rhythm, tire the eyes and cause headaches or migraines in sensitive people.
There is a "double effect", especially when working with screens: many displays and LED lights emit blue light at the same time - which puts additional strain on the eyes. Headaches, dry eyes or a feeling of overexertion are frequent consequences.
Green light and its effect on headaches
Green LED light has proven to be particularly beneficial in relieving headaches, especially migraines. Studies show that green light flickers less and causes less eye strain than other light colors.
It modulates neuronal activity and can calm overactive brain signals, which helps to relieve pain. A Harvard Medical School study found that exposure to violet light reduced migraine pain by 25 percent in a group of test subjects. Although more research is needed, this suggests that violet light could also potentially be helpful
Eye-friendly lighting design: the right light for every room
To make lighting a real feel-good factor, we recommend selecting light specifically according to function and length of stay.
Here are a few practical tips
:1. living room & Bedroom - warm white relaxes the eyes
Warm white light (approx. 2700-3000 K) is suitable for rooms where the focus is on relaxation. It creates a pleasant atmosphere, puts little strain on the eyes and promotes a calm evening mood.
2nd kitchen & Bathroom - neutral white for clarity without sensory overload
Here, the light can be a little brighter and more neutral, but not too cold. A range around 4000 K ensures good visibility and colors without dazzling or overstraining the eye.
3rd home office & Study - balanced light with little blue light
Avoid too cold white light, which is unnecessarily tiring. Daylight white can be useful if you need to concentrate on your work for many hours - ideally combined with a blue light filter or dimmable luminaires.
4. smart lighting - light according to time of day and mood
Modern LED luminaires with CCT function (Correlated Color Temperature) or Tunable White make it possible to change the light color depending on the time of day or usage. Activating in the morning, calming in the evening - fully automatically or controlled by app.

Tips for choosing the right LED lighting
1. adapting the light color to the room: Warm white light is recommended for living rooms and bedrooms as it creates a relaxing atmosphere. In work areas such as offices, neutral white or daylight white light can promote concentration.
2. avoid blue light: Blue light can put more strain on the eyes and cause headaches in sensitive people. It is advisable to minimize the amount of blue light in the lighting, especially in the evening.
3. use of light filters: luminaires with an orange filter can help to reduce the blue light component and thus reduce the risk of eye strain and headaches. Adjusting the brightness: Dimmable LED lamps make it possible to adjust the light intensity as required and thus avoid glare, which can cause headaches.
4. regular breaks and eye relaxation: Regardless of the light color chosen, it is important to take regular breaks and relax your eyes, especially when working on screens for long periods of time.
