In conclusion, results showed a concurrent increase of both visual fatigue and arousal under high screen luminance.
While an upsurge in visual fatigue
– reflected by a reduction of the number of eye blinks
– might be a bad news for our eyes, the rise of arousal
– reflected by improved reading performance
– has a quite good connotation.
For example, the fact that participants showed faster reading times under high screen luminance without impairing comprehension is definitely good news
