LED light technology (light-emitting diode) is one of the biggest innovations in recent times. It has many advantages: it has a low energy consumption, it protects the environment, it reduces the need to replace the bulbs and the electricity bill will be much lower.
The same LED technology that is used to make light bulbs is also used as a lighting system for digital screens, such as the screen of your phone, tablet, TV or laptop.
Undoubtedly, LED technology brings many undeniable advantages, but does this type of lighting also bring disadvantages?
Is the LED light harmful to the eyes?
Light emitting diodes, LEDs, use short light waves, most of the time the light emitted being a “cold” one. This cold light comes from the blue side of the color spectrum.
In a report by ANSES (National Agency for Food, Environmental and Occupational Safety in France) quoted by Daily Mail, we find an important statement: “that prolonged, continuous exposure to this light may be enough to damage a person’s retina”.
Another study, conducted by Dr. Celia Sancez-Ramos, exemplifies the danger posed to animals by exposure to LED light. Specifically, the retinas of the animals in this study were exposed to LED screens for three months, with cycles of 16 hours of light and 8 hours of darkness. This study showed a 23% retinal cell death.
These are not the only studies that show that exposure to LED light damages the retina and your eyes health, but it is enough for us to consider that this aspect is as real as possible.
Artificial blue light vs. natural blue light
We know very well that blue light is also found in the natural environment, coming from the sun. Here's a common question about blue light: "Does it affect your eyes just as much?"
The difference is in the way we experience sunlight. The sun gives us light, but we seldom look directly at it, as this could cause irreparable damage to our eyes.
Artificial blue light, which comes from light bulbs or from digital screens, it is not as intense as the sun. However, people often look at these sources of blue light for long periods of time and from a much closer distance. For this reason, artificial blue light is much more harmful than blue light from the sun.
How can we protect our eyes from LED light?
Unfortunately, we can't give up the phone, laptop or TV, they are part of our life and help us to be always informed and to communicate.
Fortunately, there is a very efficient and accessible solution, through which we can reduce the degree of exposure to blue light emitted by digital screens or light bulbs, more precisely, computer blue light glasses, which are able to neutralize most of the blue light.
Gunnar glasses technology
Gunnar offers both models of computer blue light glasses and models of gaming glasses, which can be worn when using your favorite devices. They block blue light and minimize side effects caused by prolonged exposure to blue light.
Moreover, Gunnar is the reliable brand of computer glasses whose lenses benefit from a patented technology. The models of Gunnar glasses are designed to block blue light, reduce eye fatigue, prevent dry eyes and irritate the eyes, minimize reflections and help you sleep better.
These benefits of Gunnar glasses result in clarity and improved focus, allowing you to perform better, whether you're using them professionally, in the office, or using them in a gaming session.
