3 tip to know What is blue light?

What is blue light

we all hear about the famous blue light on the occasion of the inclusion of a multitude of electronic devices that make life easier for us. But we need to know that it’s blue light and how it can affect us in the future

The blue light

What is blue light and its wavelength

Faced with the increased exposure of our retina and maculate to so-called violet blue light, we all wonder what is blue light? we can protect ourselves from emissions.

We all know by now the relationship between violet blue light and macular degeneration (DMAE) or computer visual syndrome (SVI).

Today we all suffer exaggerated bombardment of the blue light emissions produced by the different devices that surround us computers, laptops, smartphones, flat televisions and tablet.

These electronics have entered our lives to be part of it. in a word they have come to stay.

We cannot deny that these devices have changed our lives, allow us to relate remotely, are basic in our work environment and if that were not enough they are already part of our entertainment.

its usefulness is undeniable. therefore to stop using them is not an option that we don’t even consider.

like all technological changes the virtual world and the Internet is the window a world from which we can only imagine the technological advantages that it will present to us in the future.

but every advantage has some drawbacks. the drawbacks of this technological age is the increase in exposure for our vision of the violet blue light hen.

Is violet blue light the same as ultraviolet light?

What is violet blue light

The answer is no. They are two different types of lights with different wavelengths and one is noticeable to the human eye and the other is not.

ultraviolet light is below the wavelength perceived by the human eye between 10 nm and 400 nm.

In addition, ultraviolet light is a potentially more dangerous light for health than blue light.

Violet blue light ranges from wavelengths ranging from 380 nm to 475 nm It is therefore the lowest part of light that the human eye can perceive but is perfectly visible.

Exposure to blue light in the long run will only cause damage to our vision and in our retina increasing the possibility of pathologies or eye syndromes in the long half term but is not carcinogenic or causes any other problems.

This is not the case with ultraviolet light on which we can say according to different dermatological studies carried out that it causes premature aging of the skin and responsible for 5% to 10% of skin cancers.

But what is blue light?

Blue light is the lowest part of the visible spectrum that the human eye is able to perceive length emitsatwavelengths ranging from 380 nm to 475 nm.

Naturally we can find it in sunlight and artificially we find it in the light emitted by our electronic devices such as:





It is therefore very easy to infer that the problems caused by the emission of blue light are not so much because of that light as it is because of the increasing number of hours we spend in front of these electronic devices.

therefore the blue light Colombian government is found in our day to day naturally and it is not at all harmful. problems with blue light are generated by overexposure to electronic displays where we are immersed in recent decades.

Because blue-violet light is harmful to our eye health?

The first thing we have to do is that all the blue light on the spectrum is not harmful to approximately 25% of the white light we see is blue.

Within the range of blue there are different tones and wavelengths and not all of them are harmful to our health.

turquoise blue light.

It is the most beneficial light of the blue spectrum regulates our biological clock that tells us the sleep cycles.

It is fundamental in the perception of other colors and regulates visual perception

It is essential in cognitive processes such as memory.

It also regulates body temperature.

How we can see being subjected to the wavelengths of turquoise blue light provides countless benefits for our body and well-being

purple blue or violet blue light.

Purple blue or violet light is the one that gets into a lower wavelength and besides these wavelengths are the ones that are emitted more vigorously so we call it high-energy visible light.

This light can cause different disorders and pathologies so it is essential to protect against it.

We know it’s the blue light. What can we do to block it.

Clearly, at this point no one advocates the non-use of different electronic devices how important work and entertainment are to our lives.

But that would be good when using these devices use some element of blocking such light such as protective screens or glasses that block light.

Without a doubt our eyes will thank us, for let us remember that the cells of the retina do not regenerate and will accompany us forever.

Obviously patients with diabetic or diabetic symptoms haveto take spatial care when being at-risk patients.
