But what is blue light? Digital devices emit higher levels of blue light, which can lead to eyestrain, fatigue and reduced concentration.      Designed for those who spend lots of time on screens, these glasses provide extra protection. But how much blue light is too much? We're exposed to more blue light than ever due to LED lights and digital screens, and too much can affect our sleep cycle. Blue light in the day helps us stay awake, while less of it at night helps us sleep better.
