The effects of blue-light filtration on sleep and work outcomes. Journal of Applied Psychology

Science shows wearing blue light filtering glasses when using electronics improves sleep, but can they also impact work performance? 

Researchers conducted one study with 60 managers and another with 70 call center representatives. Participants received either blue light or fake glasses and wore them for at least 2 hours before bed for 2 weeks if reading or using electronic screens and completed surveys throughout. 

 Results? In both studies, the people who wore the blue light screening glasses slept more and had better sleep quality than those who wore fake glasses. These improvements in sleep led to more work engagement, better work performance, and more behaviors associated with teamwork. They also found that these effects were stronger for those who wore blue light glasses and like to go to sleep later “than most people do” as opposed to earlier. 

Blue light can disrupt the body’s natural sleep cycle and internal clock. Therefore, sleep at night and wear your blue light blocking glasses if using electronics 2 hours before bed. Regulating this cycle can affect so many areas of your life—your health, job performance, and work relationships!
