Why We Need Blue Light Block Lens?

Blue light is everywhere - While manmade sources of blue light include fluorescent and LED lighting, flat-screen televisions, and the display screens of computers, electronic notebooks, smartphones and other digital devices; our main source of blue light is the sun, and we are most exposed to it when we are outdoors during daylight hours.

It contributes to digital eye strain – While this is less dangerous than the effects of the blue light generated by the sun, digital eye strain is something we are all at risk of. Most people spend at least 12 hours a day in front of a screen, though it takes as little as two hours to cause digital eye strain. Dry eyes, eye strain, headaches and tired eyes are all common results of staring at screens for too long. Blue light exposure from computers and other digital devices can be reduced with special computer glasses.
