We protect our eyes from the sun's rays, but what about blue light?
We are exposed to this light daily because it is diffused by our computer screens, telephones, but also by the sun. We can therefore say that we are exposed to it constantly during the day, especially since our screen time is only increasing.
But then, how can we protect our eyes from blue light?
What is blue light?
Blue light is composed of blue-violet light and blue-turquoise light. The first accelerates the aging of the retina, the second is essential for the body because it contributes to a good sleep cycle, acts on mood and well-being.
Blue light is part of the light our eyes receive daily, and is the most energetic, which makes it potentially dangerous for our eyes.
Potentially dangerous because we are exposed to blue light outside, the sun being the major source of emission of this light, but also inside through the LEDs of our lighting and our screens.
How does blue light impact our vision?
Blue light has an impact on our eyesight because it accelerates the aging of the retina and therefore has an impact on the quality of our vision in the long term. The proliferation of LED screens: TV, tablets, phones, computers, overexposes us to this blue light.
In the short term, our eyes get tired more quickly, we are faced with chronic visual fatigue which can create headaches, feelings of fatigue, blurred vision or even dry eyes. In the medium term, this can affect our mood and even our sleep. In the long term, there is an increased risk of age-related macular degeneration.
How to fight harmful blue light?
To combat blue light, we can take easy action. We just need to reduce the amount of light that is harmful to our eyes by wearing glasses that block this blue light.
The glasses will filter the light that is harmful to our eyes, namely blue-violet light, while letting through the blue-turquoise light which plays an essential role in our well-being.
To further protect your eyes, beyond wearing so-called "anti-blue light" glasses, you can do a few things every day. Some software and applications exist to adapt the brightness of screens during the day. It is especially in the evening that you need to reduce this blue light so that the sleep hormone is activated and falling asleep happens more quickly.
