Blues And Reds Light is the most harmful visible lights. But why we need to care more to blue lights?

Blue LED light sources are becoming increasingly common in today's environment. Exposure to blue light comes from a variety of technologies including computers, televisions, and lights. Much of the harmful exposure arises from light-emitting diodes (LEDs).

Today, many white LEDs are produced by pairing a blue LED with a lower-energy phosphor, thereby creating solid-state light (SSL). This is often considered “the next generation of illumination” as SSL technology dramatically reduces energy resource requirements.

 

 

Increasingly, people are exposed to blue LED light via everyday technology. The 2015 Pew Research Center study found that 68% of U.S. adults own a smartphone and 45% own a tablet. The study also found that levels of technology ownership vary by age; 86% of Americans 18-29 and 83% of those 30-49 own smartphones. 

Younger Americans also use high rates of blue light technologies. The survey of Common Sense Media in 2013 also demonstrated that 72% of children age 0–8 years old used mobile devices for watching videos and playing games. Moreover, 93% of teens owned a computer or had access to one at home. In contrast, computer ownership rates are lower for older Americans.

 

 

So for simply put, why we need more prevention of blues than the reds because the screen gadgets we use now has more blue lights, as the LED screen industries has added more blues for better energy consumptions for the latest gadgets. And, with the the survey around the U.S alone, we can see that the increasing usage of the screen gadgets by the people and the trend is seems not going to go down at the near future. This trend also going to be followed to the rest of the world and we can see it will be harming more and more people at the future.
