Blue light from electronics is linked to problems like blurry vision, eyestrain, dry eye, macular degeneration, and cataracts. Some people have sleep issues.
You see, your eyes are able to destroy white/yellow light and prevent it from reaching the retina. But, it isn't adapted to destroying blue light so therefore, the blue light reaches your retina and breaks the retina down. During the process of breaking it down, toxins are produced which further reduces eyesight.
