Blue lights are part of our daily lives. With the LED technology that surrounds us, we find anti-blue light glasses to protect us from these slightly dangerous light rays.

When it comes to short periods, the dangers are not (very) significant. On the other hand, when you work with a computer screen, tablet or Smartphone on a daily basis, it is no longer the same thing. Homes have on average 5 to 6 screens  , which leaves plenty of opportunities to consult information, read articles or work on your PowerPoint presentation.

The big problem we encounter is when we abuse blue light . You can have a damaged retina that is much more tired (itchy eyes, headaches, etc.).

To remedy this, we have blue anti-light glasses.

Efficiency depends on the wavelength filtered

The pair of blue anti-light glasses requires special attention on your part. Before buying this type of light, you will need to make sure that there is a sufficient wavelength.

The shorter the wavelength, the more harmful it is according to experts and engineers on the subject. To briefly explain, blue-violet light will have a light spectrum from 380nm to 460nm.

For comfort in all circumstances, you should have a pair of glasses that is able to filter this type of wavelength. This is particularly the case for people who play gaming.

Identify the level of protection you need

To know precisely this information, you will have to ask yourself the right questions: what are you going to do with this pair of glasses? Is it for office automation? Is it for gaming? In these two cases, the need is not the same.

Indeed, gamers (video game players) have very specific needs. They will need protection from the shortest wavelengths.

For people who use the glasses a few minutes in the evening before sleeping, or for one or two hours a day, it is possible to turn to products that have a classic blue light filter.

How to easily test a blue light filter?

We draw your attention to the information you find on the Internet. Some are reliable, others are not.

To test filters, you must rely on specific and valid criteria.

How to test physical blue light filters?

Before passing the test phase, you should have as much information and information as possible about the blue light filters. If you are planning an Internet purchase, contact support and request the wavelength filtered by the product.

Once the anti-blue light glasses have arrived at your home, you will be able to test the filters using two light spectra.

By carefully studying the two light spectra, you will realize that there is a light spectrum where blue light is present "normally" and a second spectrum where blue light is almost absent . This is a sign that the blue light filter is working well.

How to test anti-blue light software?

Blue light filter software is increasing in this market. You can opt for applications that are available on Smartphone’s, tablets, tv and computer.

More and more Smartphone manufacturers have decided to integrate functions adapted for screens directly into the software . Each solution is proprietary, but allows you to have a smartphone that has this blue light filter .

To find out, just look at two light spectra with and without the filter activated. You will quickly notice that there is a filter that does not contain blue unlike another.

To conclude

It is not difficult to know precisely and with certainty whether the glasses have a blue light filter or not. However, what will make all the difference is the quality of this filter . This is why it is essential to know the manufacturer's filtration rate.
