â˜…WHAT PERCENTAGE OF BLUE LIGHT DOES OUR COMPUTER GLASSES BLOCK?
Kirka computer glasses focuses on blocking off the High-energy blue/violet spectrum (400nm - 430nm).
This is the most harmful part of the light spectrum and is the part that we are blocking the most - at 90%.
We then let through more of the Low-energy blue spectrum (430nm - 495nm).
It is relatively less harmful compared to the High-energy blue region and only 30% of light in this region is blocked so you can still see most blue as blue through our glasses.
This is why we can achieve a low color distortion characteristics for our lens.
