In the simplest terms, blue light blocking glasses are glasses designed to protect your eyes from blue light emitted by electronic devices. Why? Well, according to research, prolonged exposure to blue light can result in digital eye strain, which could eventually lead to premature ageing of the eyes and blindness.
With the world becoming much more digitized, more people are glued to their screens now more than ever. Thus, more people are susceptible to experiencing issues with their eyes at this age.
Before delving into what exactly blue light blocking glasses are meant to do exactly, you need to understand what blue light is.
What Is Blue Light?
If you're familiar with the different colours of the rays that make up the sunlight, then you'd know that each of them varies in wavelengths & energy. The rays of the red spectrum have a longer wavelength and less energy intensity, hence, they are less harmful. However, the rays of the blue light have a shorter wavelength and more energy.
Usually, blue light rays appear white to the human eye, so sources of white light are generally harmful to the human eye. This is because they usually contain large amounts of blue rays.
Some of the most common sources of blue light are as follows;
- Fluorescent lights
- LED light
- Flat-screen, LED television
- Mobile devices; Phones, tablets, etc.
Even though UV rays from the sun contain a larger amount of blue rays, there has been a growing concern for those emitted from mobile devices. Most importantly, the long term effects are what is most considered, because of the proximity to these devices. With more people being glued to their screens, the absorption rate is more compared to that of the sun.
