LED lights damage eyes and disturb sleep, European health authority warns

French Agency for Food, Environmental and Occupational Health & Safety, ANSES, warns about retinal damage related to blue light emitted by LED sources.

Although you probably are already aware of this because you receive our newsletters, most people have not yet recognized that the light emitted by device screens can cause retinal damage and accelerate macular degeneration.

The fact that an institution, no matter who it is, reveals the facts about this damage does not change the reality. We know very well, several institutions have outright ignored it, even some "respectable” ones we consider, have denied it since the University Complutense of Madrid (UCM) team discovered the fact that LED light from screens can cause retinal damage, back in 2013. The only thing that has changed since then is that emissions have increased and precious time has been lost where billions of children and adults continue to receive toxic emissions that damage their vision and accelerate the risks of irreversible blindness.


We are walking on the razor's edge as a society and we do not realize the consequences of the huge increase in usage of screens, already estimated at more than 11 hours a day, reported in many countries around the world. We should think about what kind of a society we want for our children and protect them while we are still on time.

The reality is that nobody can recover the cells of your retina or the vision that you will lose by continuing to use screens, without adequate protection. The other reality is that each of us will either pay the price as a result of not acting to solve the problem or, we will enjoy our lives when we do the right thing, the sooner the better.

We know you are well informed and you already know that the LED light from a lighting fixture you receive is 3 times lower than the one received by your eyes from your mobile phone, as you saw in our previous newsletter.


The ANSES study focuses on the emissions of LED lighting sources and states that there are also risks from screens at a lesser level, which is a statement that is clearly contradicted by the measurements we described in our previous newsletter. Considering the description we provided, one only needs to have a basic knowledge in physics to understand. The amount of energy received by the eye is also related with the distance to the source, which is much less for smartphones and tablets. That is, if the facts stated point to LED lights being dangerous for our vision, then the screens are obviously much worse even though they emit less amount of light. Simply put, when we look at screens, the source is at a much closer distance to the eye and, this factor is the most critical, above all.

Being well informed makes the difference.
