About Blue Light

Introduction:

With the increase in electronic devices that we use professionally or privately, there are more and more unnatural sources of blue light in our everyday lives, such as: E.g. computer and laptop screens, LED lamps, smartphones and others. They accompany us all day and often throughout the night, when we would no longer naturally consume blue light. Due to the increased exposure, the question now arises as to whether blue light can also have a harmful effect on the human organism?

 How harmful is blue light?
It is already known that dry and overstimulated eyes are a sign of excessive screen consumption. The bright and high-energy blue light can also influence how we fall asleep by inhibiting our melatonin production. As a result, the blue light can quickly lead to an inability to fall asleep. Studies show that blue light can cause damage to our retinas. Nightly series marathons or writing homework on the computer in dark light are therefore not the best way to pass the time for the health of our eyes.

As with so many things, blue light seems to be about quantity. Indirect daylight usually does not cause retinal damage. Even an hour or two in front of the screen doesn't hurt us at first. But the longer we spend time on our laptops and cell phones, the higher the risk that our eyes can suffer.

And the pandemic in particular has promoted exactly that, as a representative survey of 2,032 test subjects shows: 36% said they spent more hours in front of the screen than before Corona. Among 18-24 year olds it is even more than 50%.

 

We look more and more often at our smartphones or tablets. Or watch TV. For our eyes, this means looking closely at illuminated screens for many hours, day after day. Experts speak of digital visual stress. When you concentrate on your computer, tablet or cell phone, your blink frequency drops, meaning the tear film can no longer be distributed evenly over your eye. The result: the eyes become dry, they burn, itch and turn red.

Screens emit blue light!
The displays of cell phones, tablets, etc. today primarily use light-emitting diodes (LED = light-emitting diode) for background lighting. To create white light, they primarily mix yellow and blue light. And blue light in particular can strain the eyes.

Why is blue light different than, for example, sunlight?
The light that hits our eyes can be divided into visible light and non-visible radiation in the ultraviolet and infrared ranges. The spectrum of sunlight is evenly distributed across the entire wavelength range. The spectrum of LEDs, on the other hand, is clearly in the blue range. Unlike UV light, which is absorbed in the front of the eye, high-energy blue light penetrates the eye almost unfiltered and onto the retina. Due to the widespread use of LEDs (for example in lamps), their different spectral light composition and our changed visual behavior, we are now more exposed to blue light than before.

Does blue light damage the eyes?
Studies on the effect of blue light on the eyes show that blue light could cause damage to the retina and visual cells. Oxygen radicals are created that can lead to the death of visual cells. Damage that cannot be repaired because dead visual cells can no longer be replaced. This means: visibility worsens. However, how much blue light is necessary for this is not yet clearly defined.

Unveiling the Blue Light Spectrum:

Blue light is an integral part of the visible light spectrum, consisting of various wavelengths. However, not all blue light is created equal. Dive into the blue light spectrum and pinpoint the specific rays that can be detrimental to your well-being.

Health Concerns:

1. Digital Eye Strain: Learn how prolonged exposure to screens can lead to digital eye strain, causing discomfort, dry eyes, and blurred vision.

2.Sleep Disruption: Explore how evening exposure to blue light can disrupt your sleep patterns by suppressing melatonin production, making it challenging to get restful sleep.

3.Retinal Damage: Understand the potential risks associated with age-related macular degeneration (AMD) and retinal damage due to extended exposure to high-energy blue light.

4.Skin Effects: Discover how high-energy blue light can contribute to skin aging and pigmentation issues, and why protecting your skin is crucial.

Is there a connection between blue light and myopia?
Myopia is increasing sharply. In Europe, almost every second school child is now affected by eye abnormalities, and in Asia, 90 percent of young people are affected. However, according to the latest findings, it is not the blue light that is to blame, but rather looking closely at the screens of cell phones, tablets and computers, the so-called close work.

 

Why Use Blue Light-Cutting Glasses?

Reduced Eye Strain: Find out how blue light-cutting glasses can significantly reduce digital eye strain by filtering out harmful blue light, ensuring more comfortable screen time and increased productivity.

Enhanced Sleep Quality: Learn how wearing blue light-cutting glasses in the evening can protect your sleep quality by preventing the disruption of your natural circadian rhythms.

Protection Against Retinal Damage: Explore how these glasses offer an additional layer of defense against potential retinal damage and age-related macular degeneration, preserving your visual health.

Mitigation of Skin Damage: Understand how blue light-cutting glasses can help shield your skin from the premature aging and pigmentation issues associated with harmful blue light.
