PEC University of Technology in India has completed a comprehensive study on the effects of blue light exposure on human cognitive performance.
Specifically, study participants were exposed to LED screen with Eyesafe RPF30 level filter compared to baseline LED screen.
The results of this study may be found here and are highlighted below. Prolonged exposure to blue light from LED was found responsible for:
• unpleasant mood
• inducing sleep disorders
• increased inability to hold information i.e. it affects memory
• decrease in the reaction time during certain tasks given
Use of Eyesafe RPF30 was shown to reduce the above effects. These results are positive and open up additional areas of future study.
“Results have shown that there was a significant difference in EEG delta theta activity, mood, sustained attention (action time task), short term memory (verbal memory task), and active memory (visual memory task) for two types of screen interfaces. Continuous exposure to LED screen has led to decrease in frontal region delta theta activity and increased alertness. Exposure to (RPF30) blue light filter has elevated memory performance and mood in participants. Thus continuous exposure to blue light, emitted by LED screens was found harmful for mood, memory performance, attention and sleep.”
We are encouraged by these results and are committed to ongoing research. We currently are developing additional research for the industry.
