Filtro luce blu: perché è diventato fondamentale?

Blue light filter: because it has become fundamental ?

Have you ever thought about how much our way of life has changed in the last 20 years?

Technology has transformed every aspect of our daily lives.

From online shopping to video calls with our loved ones, from distance learning to smart working…

But the worst is what happened to our evening habits…

In the evening, many people have the habit of using their smartphones, PCs or watching TV even until before going to sleep…

What do all these activities have in common?

THE BLUE LIGHT.

Our eyes, our sleep, and our health are fighting a silent battle against an invisible enemy: blue light.


Think about the typical evening we live in these modern times…

PC, TV, social networks, video calls with friends or family, a film on Netflix… all these activities expose us to the screens of our electronic devices, which emit large amounts of blue light.

But these are not the only sources of blue light to which we are exposed in the evening…

Even simple LED bulbs, which replaced halogen ones in 2018, emit high amounts of blue light…

What does this blue light do to our body and why is it necessary to filter it?

We were never exposed to blue light until a few decades ago…

Until a few years ago, phones had much smaller, less bright screens and no LED technology…

Same thing for TVs.

Besides that, until a few years ago there were no streaming platforms like Netflix and Social Networks were not yet as widespread as they are today…

The bulbs were halogen and emitted an almost negligible amount of blue light compared to the LED ones of today…

The worst part?

These habits are constantly increasing.

Young people are going out less and less and are spending more and more time scrolling through social networks or watching television…



More and more workers have to sit in front of the PC, that is, exposed to an ever-increasing amount of blue light…

What does this mean for our body and why do we need a filter for this blue light?



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, without any filter…

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 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 brains...

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 with a filter.

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?

Here's What Studies Found About a Blue Light Filter

More studies have revealed something surprising…

Filtering out blue light 2 hours before going to sleep can make these problems disappear.

This means no tired eyes, burning eyes, difficulty falling asleep, or trouble staying asleep.

We spend 1/3 of our life sleeping and the other 2/3 are influenced by how we spend the third we sleep…

Good quality sleep allows us to be rested, alert and productive the following day.

More and more people feel tired in the middle of the day and have less energy, and blue light is the main culprit of this problem.

This study, conducted by Columbia University in New York, has discovered something surprising about a blue light filter.

People with insomnia problems were taken and tests were done by making them wear glasses with a blue light filter before going to sleep.

Tests were done with both glasses that actually filtered blue light and “placebo” glasses, which didn’t actually filter blue light.

People in the study reported better quality sleep, a shorter time to fall asleep, and deep, restful sleep when they wore the blue-light-filtering glasses.

These blue light filter glasses are the only option for blocking the blue light we are exposed to in the evening.

Blue light comes from all the electronic devices we are exposed to in the evening and from LED light bulbs at home.

The only option to block all this blue light, protect our eyes, and improve our sleep, is to prevent this blue light from hitting our eyes.

For this reason we also brought the No Blue Light Glasses and we've decided to give you a 60-day trial to test these improvements, risk-free.

By wearing these blue light filter glasses, you will be able to:

• Protect your eyes. The filtering of blue light by No Blue Light Glasses allows us to continue following our evening habits. You can use your smartphone, PC or watch TV without having eye discomfort caused by blue light, such as burning, dryness or tearing;

• Improve your sleep. By not detecting blue light, our body will naturally produce melatonin, making us fall asleep in a few moments and giving us a deep and restorative sleep;

• Regulate the circadian rhythm. Blocking blue light in the evening helps us maintain a regular biological clock. This will help us improve our sleep and be more rested and productive the following day;

• Fight headaches. Large amounts of blue light can lead to migraines or headaches. With the blue light blocking provided by No Blue Light Glasses, you can combat them.

Hundreds of people have already purchased these glasses so far.

There was only one case of a person asking to return them within 60 days.

All other 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.

At first you have to get used to it, especially if you don't wear glasses like me. I use them two hours before going to sleep if I have the lights on, I use my cell phone or the TV. I fall asleep without even realizing it. Recommended for everyone!

Great buy

I found them very good, my sleep was much deeper and more restful. I had no trouble falling asleep before, but wearing the glasses to read in the evening or watch TV I felt a relaxing effect and I fell asleep much earlier than usual. I will also buy them for my mother and son who have trouble falling asleep. Thank you

Believe it or not, it's true.

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, highly recommended!

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.
