WHY DOES BLUE LIGHT CAUSE EYE STRAIN?
When blue light enters the eye, it scatters before reaching the retina. Our eyes work overtime trying to focus this scattered light, which they cannot do.
Imagine running a marathon where someone keeps moving the finish line back. That’s what your eyes are going through as they’re trying to focus blue light. 
Depending on brightness, this out-of-focus blue light can appear as glare. The more blue light in the environment, the greater the glare.
If you've ever been in the snow or out at the pool without sunglasses, you're familiar with the strain glare can put on your eyes. |
