I can't agree with NY times because I can't read on my Nexus Tablet more than 20 minutes.
"The New York Times explains:
Today's screens are definitely less tiring to look at than older displays, which refreshed the image much less frequently, causing a flicker. Carl Taussig, director of Hewlett-Packard‘s Information Surfaces Lab, said the 120 Hz refresh rate typical of modern screens is much quicker than our eyes can even see.
"The new LCDs don't affect your eyes," Mr. Taussig said. "Today's screens update every eight milliseconds, whereas the human eye is moving at a speed between 10 and 30 milliseconds."
