Luce blu emessa dagli schermi: quali sono gli effetti su occhi e sonno? Come è possibile proteggersi?

Blue light emitted by the screens: what are the effects on eyes and sleep ? how you can protect yourself ?

For a few decades now, we have been increasingly exposed to the blue light emitted by screens.

What are they? the effects of this blue light on our eyes, sleep and health?

How can you protect yourself?

Unfortunately, The damage that the blue light emitted by screens can cause is many and affects people differently.

In modern life we ​​are exposed for several hours (sometimes most!) to different types of screens: smartphone screen, PC screen, television screen, tablet screen, etc.

What do all these screens have in common?

All of these screens work with LED technology, which is known to emit very high amounts of blue light.

Exposure to this blue light causes more problems...

Some people have burning eyes after hours spent in front of a smartphone, TV or PC screen…

Some people have trouble falling asleep due to the low levels of melatonin that exposure to blue light causes…

There are those who cannot sleep a deep and regenerating sleep but wake up often at night…

These are usually the first symptoms of blue light damage.

In the modern world we are constantly exposed to the blue light emitted by smartphone screens, computers and even of LED lighting such as light bulbs in your home.

What are the risks and damages to our health that this exposure to blue light entails?


First things first… what is blue light and why is it harmful?

Blue light is a natural component of sunlight.

In nature it is emitted only by the sun during the central hours of the day.

However, for a few decades now it has also been emitted in large quantities by the screens of our electronic devices such as smartphones, TVs, PCs, tablets, etc.

The problem?

Our bodies are not designed to handle this prolonged exposure to blue light, especially in the evening.

We have seen that the sun emits blue light only during the central hours of the day…

In the morning and at sunset, however, as you can see below, the light emitted by the sun contains very small amounts of blue light.


However, for a few decades now our body has been exposed to blue light even in the evening…

This can cause damage to our body, which often begins to manifest itself with these symptoms, which vary from person to person:

• Difficulty falling asleep;

• Insomnia;

• Light and unrefreshing sleep

• Visual fatigue;

• Dry eyes;

• Blurred vision;

• Frequent headaches;

• Difficulty concentrating.

These symptoms are often underestimated…

However, In the long term, excessive exposure to blue light from screens can lead to more serious damage to the retina of our eye and alter our biological clock.

This can cause an worsening of the symptoms listed above.


Blue light damage to sleep

53% of Italians have problems with sleep, as reported in this article from “Il Sole 24 Ore”...

These sleep problems have literally exploded in recent years, the same years in which our exposure to blue light has increased.

Let's see why…

The damage that blue light causes to our sleep is “indirect”.

What does it mean?

It means that Exposure to blue light does not cause any damage to our sleep, but these are caused by the hormonal imbalance that being exposed to blue light causes in our body.

Let's take a closer look at how it works.

The blue light emitted by the sun during the central hours of the day serves to communicate to our brain that it is daytime and therefore keeps us awake and active.


To do this, our body produces cortisol, also known as the “stress hormone”.

At the same time, our brain blocks the production of melatonin, also known as the “sleep hormone.”

In the evening, however, this process is reversed:

The absence of blue light after sunset tells our brain to produce melatonin, the hormone that has the task of making us fall asleep in a few moments and making us sleep well.

At the same time, the production of cortisol, the hormone that keeps us awake and active, is blocked…

Unfortunately though, this doesn't happen anymore nowadays…

The blue light emitted by the artificial lighting in our homes and the screens of our electronic devices tricks our brain:

By detecting this artificial blue light, our brain thinks it is still daytime…

This blocks the natural production of melatonin.

The result?

Trouble falling asleep and light, unrefreshing sleep.

This leads to being less productive during the day, sleepy and with little energy.

Many people are told that they are lazy or unmotivated, but the reality is that they may be having these sleep problems caused by overexposure to blue light in the evening.


Blue Light Damage to the Eyes


The damage that blue light causes to the eyes is instead “direct”.

The burning sensation and tiredness are the most common.

Our eyes were not “designed” to be exposed to blue light after sunset.

In the modern world we live in, we bombard our eyes with blue light until we go to bed.

This also happens at close range from screens through the use of PCs and smartphones…

In addition to burning and tiredness, there are other damages to the eyes caused by blue light…

When we look at the screens of our electronic devices, we blink less.

This often causes dry eyes and eye strain.

Sleep and eye problems are the most common, short-term damage caused by blue light.

However, there are other medium and long-term damages that exposure to blue light causes.

Let's see what they are before seeing how to solve all these problems naturally, without drugs and without supplements.



Medium and long-term damage caused by exposure to blue light:

1- Predisposition to the risk of chronic diseases such as diabetes, obesity and cardiovascular diseases.

The chronic lack of our body's natural melatonin, in addition to the sleep problems we have seen, can also have repercussions on our metabolism and the functioning of the body in general.

This predisposes to the risk of chronic diseases such as diabetes, obesity and cardiovascular disease.

2- Mood swings and increased risk of depression.

Poor or disturbed sleep directly impacts emotional stability and mood regulation, exacerbating existing conditions, creating new ones, and increasing stress.

3- Damage to the immune system

Evening exposure to blue light alters our body's biological clock. This weakens the immune system, making the body more susceptible to infections and diseases.

4- Reduction in cognitive performance

Artificial blue light can affect cognitive performance, causing difficulty concentrating, reduced attention span, and memory problems.


Who is most at risk of damage from blue light exposure?



The people most at risk of suffering from damage caused by blue light are simply those who receive the greatest quantities of it.

In particular, the people most at risk are:

• People who use their smartphone or computer for several hours;

• Professionals who work many hours on the computer;

• Students and young people who use digital devices for study and in their free time;

• Video game enthusiasts who spend many hours in front of screens;

• Anyone who uses smartphones, tablets or watches TV in the evening hours.


How can you protect yourself from the harm of blue light?

Protecting yourself from blue light in modern life is very complicated.

Blue light is everywhere.

Almost all people use electronic devices in the evening, even before going to sleep.

This exposes them to dangerous amounts of blue light emitted by their screens and the potential harm that light causes.

Not only that.

For a few years now, Almost all of the lighting in our homes uses LED technology.

This technology emits a very high amount of blue light.

Halogen bulbs, which emitted small amounts of blue light, were outlawed due to energy-saving policies.

In Italy this happened in 2018.

This has effectively forced citizens to install (and replace once broken) all light bulbs in their homes with LED ones.

This means that, in addition to the screens, just having the lights on at home after sunset is enough to expose you to dangerous amounts of blue light.

Below you can see the difference in blue light emitted by a halogen bulb and an LED bulb:


Did you notice the difference between the two?

The halogen bulb, although it suppressed melatonin production, did so by about 40%.

The light bulbs we have at home now do this up to 80%, double!

But this is the least serious thing…

In the last few years, in addition to having installed LED lights everywhere, we have dramatically increased the time spent in front of the screens of our electronic devices…

Recently, platforms like Netflix and Amazon Prime have accustomed us to spending several hours a week in front of the screen…


Not to mention how much the use of social networks has increased in the evening…

Facebook, Instagram, WhatsApp, TikTok and social media in general are a consolidated habit in Italian evenings.

This has dramatically increased our exposure to blue light.

To confirm the problems that blue light causes, we saw earlier the article reported by “Il Sole 24 Ore”, which states that 53% of Italians have problems with their rest.

But not only that: the increase in sleep aids reported in this study, is the confirmation:

In 2000, the global market for sleep aids was $22.5 billion.

In 2010, it was $50 billion.

In 2020, it was $81.2 billion

By 2025, it is estimated to reach a whopping $112.7 billion.

Vision problems have also grown dramatically in recent decades, to the point where today more than 1 in 2 Italians wears glasses…

What happened in the same years that I literally have sleep and vision problems skyrocketed?

The amount of has increased exponentially blue light to which we are exposed in the evening. In particular, the use of electronic devices has increased and therefore the exposure to the blue light emitted by their screens, even before going to sleep.

So let's see how it is possible to protect ourselves from the damage of blue light.


2 solutions to protect yourself from blue light


They exist only 2 solutions to protect yourself from blue light nowadays and avoid the damage it causes.

The first is to avoid all the artificial blue light that we have introduced into our homes in recent years.

It is therefore necessary to avoid the use of any device such as smartphones, TV and PCs at least 2 hours before going to sleep.

In addition to this, it is necessary to illuminate our homes only with combustion lighting sources such as fire or candles that do not block the production of melatonin.

In short, we should go back to living as our ancestors did: without any blue light after sunset and go to bed early.

This is because, even if you don't use electronic devices such as smartphones and PCs, LED lighting in our homes still suppresses melatonin production.

This is the hormone that is responsible for making us fall asleep in a few moments and for making us sleep a deep and regenerating sleep.

You might think to limit the damage by using at least halogen bulbs, but unfortunately these are no longer available on the market...



The second solution is to block blue light.

In the world we live in, it is practically impossible not to use electronic devices or house lights in the evening.

Applying the first solution would mean "cutting" our social life and going to sleep as soon as it gets dark outside to avoid exposure to blue light.

Social networks have become an essential tool for staying in touch with distant friends or family members.

The evening is also the time of day when most people are free and can unwind by enjoying a film or a TV series…

So what to do?

Fortunately, we can continue to have these habits, but it is necessary to block the blue light...

As?

I want to tell you how to protect yourself from blue light naturally.

This solution does not involve taking drugs, supplements or solutions that do not act at the root of the problem.

I personally found myself struggling with insomnia for years without knowing why…

It took me a long time to fall asleep and I had a light, unrefreshing sleep.

I always thought I was lazy and low on energy, without knowing that it wasn't actually my fault...

I didn't know the effects of blue light and the damage it could do to my body...

For this reason I did not understand what the reason for my problems was until one evening, a short vacation in the mountains, revolutionized my life...

Looking back this is what happened that night two years ago.

I am in a mountain cabin…



One of those mountain huts where there is no cell phone reception and no electricity.

So I can't use any electronic devices that evening like I usually do.

I spend the evening with my girlfriend, eating early given the lack of electricity and therefore of light bulbs…

After dinner I talk by candlelight with my girlfriend and then we go to sleep…

I'm used to my sleep problems and I don't even notice them anymore in a way.

I know that it takes me several minutes to fall asleep and that my sleep is light…

I go to bed in that cabin as usual…

That evening, however, inexplicably, I fell asleep instantly.

Not only…

I find myself sleeping like a log for 7 hours straight without waking up.

I have no idea how many years this hasn't happened…

When I wake up in the morning, I am amazed…

It doesn't seem real to me.

I wonder if I passed out the night before or what happened.

I remember getting into bed, putting out the candle we had brought into the room to light our way and that was it…

I don't remember a single moment spent in bed tossing and turning as usual.

My girlfriend tells me that for the first time she heard me breathing heavily before falling asleep, a sign that I had fallen asleep before her.

Initially I think of the mountain…

I guess being in nature was what made me fall asleep quickly and sleep soundly…

But I don't understand how this could be possible...

I don't have a particularly stressful life and I spent that day like any other day I spend in the city, simply not working.

Stunned by the issue, I continued the vacation with my girlfriend, sleeping the second night in the same cabin with the same results.

I fall asleep within minutes and sleep a deep sleep.

In the morning I feel more rested than ever!

After two nights of sleep like I hadn't slept in years and years, we continued our vacation, which included sleeping in another mountain hut in the Alps.



We arrive at the second hut and in this one the cell phones have signal.

Artificial lighting is also present thanks to a small photovoltaic panel installed on the roof.

So my girlfriend and I can get back to our evening routine…

We use social networks and video call our families, all under the light of LED bulbs installed in that cabin…

We have dinner and after having entertained ourselves with our cell phones we go to bed to sleep…

I am excited to sleep well while still being high up in the mountains and I expect to sleep as well as I have the last two nights.

But I'm wrong.

I get into bed, saying goodnight to my girlfriend and joking about the fact that the mountain makes me relax and fall asleep in a few minutes…

But that's not happening tonight.

I start tossing and turning in bed…

I wonder why I'm not falling asleep in a few minutes like the first two nights.

I toss and turn until I fall asleep.

I sleep lightly and wake up several times during the night, just like I normally do at home.

The next morning I am disappointed.

I don't understand why this night didn't go like the previous two.

I'll think about it for a moment...

What was different from those two nights in the first mountain hut?

I'm coming to a conclusion soon...

I didn't use my cell phone, there were no lights and the only light present was that of a miserable candle!

I wonder if this could actually be the cause of my sleep problems.

So I decide to do a very simple test.

That evening I don't use my cell phone even though there is signal and I force my girlfriend to have only a candle to light us, without using light bulbs.



We spend the evening, we go to bed and…

I wake up in the morning realizing that I fell asleep in a few minutes and slept without waking up during the night!

I also feel rested and full of energy just like I did two days before…

I come back from vacation and I try to inform myself on the web to understand how the light of electronic devices and light bulbs can impact my sleep in such a negative way…

I come across several articles like this which explain how Blue light suppresses the production of melatonin and therefore ruins our sleep...

I read for hours what I find until I understand the cause of my problem.

My sleep problems are caused by blue light.

I have to avoid the blue light emitted in the evening by the screens of electronic devices such as TVs and smartphones and also avoid turning on the lights at home.

During my research, I came across an article by a doctor explaining how the Melatonin has always been our "biological switch" to make us sleep.

However, since we introduced electronic devices and light even after sunset, this switch no longer works properly...

It's as if melatonin, our biological sleep switch, wants us to sleep, but blue light forces the switch to stay on, preventing us from sleeping.

So I understand that the solution to my problems is to block the blue light in the evening.

I'm looking for a solution to understand how to use my smartphone and keep the lights on in the evening without ruining my sleep.

So, reading these studies, I come across the blue light glasses…



I read everything I find online and I discover that these glasses are designed to filter the light and let through only the warm tones of light, those present in nature at sunset.

Just wear them 2-3 hours before going to sleep to prevent our eyes from perceiving blue light.

This way, my brain will produce melatonin properly and naturally, making me fall asleep in a few moments and giving me a deep and restful sleep.

I can't wait to be able to get these results every night and wake up every morning full of energy.

During this research I also understand that blue light is not the color blue light...

This is simply the part of blue light that is present in the light spectrum.

Do you know when you see a rainbow?

In this you can see all the colors of light including blue.

However, blue is not visible except under particular conditions such as in a rainbow.



I understand that it is not the blue light that is the problem. but any type of light, as blue is contained within the light.

So I understand that to solve my insomnia problems I have to block the blue light with these special glasses.

This way I can continue to follow my evening routine, watching TV and using my smartphone in the evening.

I search on the internet and buy the glasses immediately.

I received them after a few days and I can't wait to try them.

A few days later when I receive the glasses I try them on immediately, wearing them 2 hours before going to sleep.

I go to bed at the end of the evening and… I start tossing and turning to get to sleep.

The glasses had good reviews and that's why I decided to buy them…

So as I turn over in bed I begin to think that evidently the light that these glasses filter is not enough.

A few more moments pass and I finally fall asleep.

The next morning I still notice some improvement and even during the night I wake up fewer times than usual.

The glasses had actually helped me, even if they hadn't given me the same effects as in the mountain cabin.

Evidently these did not block the blue light completely and therefore the benefits were only partial.

The idea of ​​having to spend my evenings by candlelight without technology to be able to sleep as well as those nights in the mountains doesn't convince me, and so I try to understand how to block all the blue light present in the evening...

After a few days of research I came across a foreign company that produces special lenses that are still orange in color, but with almost total blue light filtering.

I contact them to find out if they have glasses that can be purchased in Italy but unfortunately Europe is not yet a developed market for them.

So I ask if it is possible to try their glasses to see if they actually work as well as they say.

They told me they could arrange international shipping (at a high price but I agree as it was the only solution for me), and that the glasses would take about 40 working days to arrive.

I patiently wait more than 40 days until one day I receive these glasses.



Almost excited I can't wait to try them in the evening.

The first impression is that the lenses are the same as those previously tested and that the vision is the same orange color.

I wear them for 2 hours before going to bed like I did with the others...

Until I wake up 6 hours later wondering how I fell asleep.

I used to take a long time to fall asleep and wake up every 3-4 hours. Falling asleep in a few moments and sleeping for 6 hours straight doesn't seem real to me!

So I immediately come to the conclusion that the lenses of these glasses really work!

The reviews of this company are true and I fell asleep in a few minutes.

The sleep I had the night after wearing them was deep and regenerating…

I finally found the solution to my problem!

I also let my girlfriend try them, but she has never complained about any particular sleep problems like mine.

She also finds that with these glasses she falls asleep in just a few minutes and feels much more rested and energetic the next morning.



I then decide to place another order for her and my mother…

Even though it costs a few hundred euros per pair of glasses, I want to allow both of them to fall asleep in a few moments and have a deep and regenerating sleep…

Not to mention that the investment is a one-time one, and does not require a continuous purchase like the melatonin that I usually supplement…

A few weeks later, while I was waiting for my girlfriend and my mother to get their glasses, I had an idea…

Why not import this company's glasses to Italy?

I think I can help people with the same problems as me to improve their sleep…

Furthermore, I can help everyone improve their sleep as virtually all of us are exposed to screens and artificial lighting in the evening.

I also think that this problem will become more and more common…

This is because the time spent using electronic devices and artificial lighting continues to increase…



It seems like a great idea and the thought of having a small company that helps people sleep better makes me excited…

If a company like this had existed before, I would have saved myself years of sleep problems caused by blue light...

So, after almost a year since I tried my first anti-blue light glasses, I brought the “No Blue Light Glasses” to Italy.

I have a dedicated line produced with the most advanced special anti-blue light orange lenses on the market, which block 97% of unnatural blue light in the evening.

The same lenses that allowed my desperate case to solve insomnia problems.

I build a website and finally start selling “No Blue Light Glasses”...

Hundreds of people have already purchased these glasses but, despite a 60-day money back guarantee, no one has ever asked for a refund!

All the people who have purchased one or more pairs of “No Blue Light Glasses” to date have been satisfied.

All report falling asleep faster and experiencing deep, restful sleep.

Like Sabrina who says:


Or Marcello who says:



Fortunately, there are ways to combat the negative effects of blue light emitted by screens after sunset.

I was skeptical and didn't believe it but I wanted to try and I bought this pair of glasses. From the first use, after about 30 minutes of wearing them, I fell into the arms of Morpheus. Since I bought them I wear them every night before going to bed and I must say that they really help me fall asleep. I can't do without them. Exceptional!!!

Beautiful and functional glasses. It's incredible how since I've been wearing them at night I fall asleep in no time even though I've always suffered from insomnia, plus in the morning I'm more awake and energetic, this means that the quality of sleep has also improved.
Gabriele is super helpful, I had a little problem with the clip I purchased because it didn't fit well with the frame of my glasses so he immediately returned it to me with which I purchased the new glasses and he also left me the clip as a gift. Good and professional.
