Blue light from LCD panels causes damage to the eyes
the verdict
OVERSTATED
true in a weaker form than the claim states
confidence 0/100
While laboratory and animal studies show that high-intensity blue light can damage retinal and neural tissues, comprehensive reviews indicate no solid clinical evidence that normal daily use of digital screens or LEDs causes actual damage to human eyes.
what the evidence does support
High-intensity blue light can damage retinal and neural tissues in laboratory and animal studies, but clinical evidence does not show that normal digital screen use damages human eyes.
