Who Invented Blue LIght LEDs And Why?

By now, it’s well known that too much blue light can have a negative effect on the human body. But what’s the history of this technology? 


Technically, blue light exists everywhere. As part of the overall visible light spectrum, most blue light actually comes from the sun. But in 2014, Shuji Nakamura, Isamu Akasaki, and Hiroshi Amano were awarded the Nobel Prize in physics for their invention of blue LED, which made it possible to light flat screen tvs, computer monitors, smart phones, and tablets. LED technology takes less energy and emits less heat, making it an ideal lighting source to save money and energy. 


Natural blue light, like the sun, has a whole host of benefits. It boosts alertness, improves memory and mood and helps cognitive function – that’s why taking a walk in the middle of the day can be a huge mood booster. But blue light in constant concentration due to the increase in screens during the day can disturb the waking and sleeping cycle, can lead to problems falling asleep at night, restless sleep, and daytime tiredness. 


People can’t always unplug – blue LED lights power screens on cell phones and televisions and are part of our day to day lives, and even more so as people are working from home and using remote learning. Blue light blocking glasses help protect eyes from the side effects of overexposure of blue light by helping to reduce eye strain and headaches and helping people  fall asleep, stay asleep and have a more restful sleep.


BluTech glasses offer the most protection when you’re not able to reduce screen time. Our technology protects against the blue light emitted from digital devices and artificial light without any color distortion. Plus, our lenses are available in prescription, non-prescription and reading glasses so everyone can benefit from blue light protection, day or night.
