How Do Livho Blue Light lenses Work?

We are in a world full of digital devices, which leads us overexposure to the electronic blue lights everyday. We all know that it is harmful to our eyes and our health. Therefore, we need to find some effective ways to reduce our exposure to the blue lights. The most convenient and effective way is to wear the blue light glasses.
Most of us have already known that blue light glasses can block the bad blue lights, but how?
Currently, there are mainly two kinds of blue light glasses in the market.They feature with either blue light blocking coatings or layered substrates.


Using Blue Light Blocking Coatings
With blue light filtering coatings on the surface of glasses, the harmful blue lights can be reflected back away from the lenses. Specifically, the coating automatically filters out blue light before it reaches our eyes so that our eyes can reduce exposure to blue lights when we are facing the digital screens. Usually, a blue light filtering coating is applied to a clear lens. These glasses are the best choice of people who don’t like lenses with colors. Still, these glasses are suitable for outdoor activities if we have to spend a considerable amount of time outside. This kind of glasses can be easily identified through the blue reflection on the outer surface of an otherwise clear lens.
Using Layered Substrates
While the second type blue light glasses protect us by absorbing the hazard blue light instead of blocking. Blue light glasses with layered substrates means adding some anti-blue light materials into the lenses. They will absorb most of the blue light that will otherwise pass through almost entirely unimpeded to our retina. Their high effectiveness is under no doubt. However, these glasses usually appear with some colors on their lenses. They will probably distort our visions to some degree. These glasses are fit for people facing the digital screen for a long time every day and they can give best protection for them.
