Blue light glasses are a relatively new addition to the world of optics. These specially designed lenses have a unique property: they can filter out the blue light from digital screens and other artificial light sources. They are therefore called "blue light glasses" because of this ability to block blue light. The health benefits of these lenses include improved sleep quality, reduced eye irritation and headaches, and protection against potential long-term damage to the retina.
What is blue light?
Blue light is a part of visible light. It ranges from about 380 to 500 nanometers, making it one of the shortest, highest energy wavelengths. Blue light comes from the sun, digital screens (computers, smartphones, tablets, and TVs), electronic device screens, and fluorescent and LED lighting. It’s important to note that not all blue light is harmful. Natural blue light from the sun helps regulate our sleep cycle, mood, and more. However, excessive exposure from digital screens and artificial light sources can have negative effects.
The scientific explanation: How blue light affects our eyes and sleep
Science has shown that blue light can disrupt our internal clock, which regulates our circadian rhythm. Our eyes have no natural protection against blue light, and almost all blue light passes almost directly through the cornea and lens and reaches the retina at the back of the eye. Overexposure to blue light can potentially damage light-sensitive cells in the retina and cause changes similar to those in age-related macular degeneration - a serious eye disease that can lead to permanent vision loss.
The effect of blue light in a digital world
Our modern lifestyle has significantly increased our exposure to blue light. Many people spend eight hours or more a day in front of a computer screen, smartphone or tablet. These devices emit a large amount of blue light. While blue light in appropriate amounts is necessary for optimal health, as mentioned, too much blue light from digital light sources can have negative consequences, especially for our eyes and sleep cycle.
Who needs protection from blue light the most?
Anyone who spends significant amounts of time in front of digital screens can benefit from blue light protection. This includes students, office workers, gamers, and those who regularly use smartphones and tablets for extended periods of time. People who already have eye problems may also be at higher risk for further damage from blue light.

The benefits of bluelight glasses
One of the most talked about advantages of blue light glasses is improved sleep. By blocking harmful blue light that can disrupt our circadian rhythm, blue-light filtering glasses often improve sleep quality. Harmful blue light can also cause eye dryness and irritation, which can be alleviated by wearing blue-light glasses.
Studies have shown that blue light filtering has positive effects on productivity and work performance. By reducing eye strain, blue light filtering glasses can reduce fatigue and discomfort, which can affect one's focus and concentration.
If you work in front of a screen for many hours, you may experience eye strain, headaches and fatigue, which can affect your productivity and well-being. By blocking blue light, our bluelight filter can counteract such discomfort and thus help improve your work experience.
With a bluelight filter, you can therefore work longer without experiencing discomfort, while also reducing the risk of long-term damage to your eyes.
Conclusion: Should you wear blue light glasses?
Blue light glasses are a good investment for those who regularly spend time in front of digital screens. While they are not a substitute for a healthy balance between screen time and offline time, or periodic breaks to rest your eyes, they can be a helpful solution for many.
