So what goes behind the making of these advanced glasses? What is the science that blocks the blue light glasses? How do blue glasses work? These are some of the questions that might be twisting your mind with the thought that how the blue light that is emitted from digital devices, lights etc. can be blocked merely by eyeglasses. Let us understand these glasses in detail. But before that, it is important to understand the concept of blue light also.

What is Blue light?

Blue light is the short wavelength of light rays and forms part of the visible spectrum. Among all the colours that constitute part of the light rays, blue light is visible and makes the sky appear blue. They fall between 400-550 nm of the spectral range.  Therefore, this is the range of the spectrum that is harmful where the blue coloured rays are available.

Now, if you happen to block this range of visible spectrum somehow, then you will not be able to see or experience the blue light and its affect.  Thus, blue glasses do exactly the same job. They are well-equipped to understand the range of blue light and effectively blocks blue light from entering the eyes.  By this, it means that the blue light glasses are able to block the spectral range of 400 to 550 nm of light rays. When the blue light is blocked from entering the eyes, we do not experience any effects of blue light and are able to perform our jobs with ease. Therefore, the use of blue light filter glasses can save you from all the perils brought by the blue light.
