Oct. 28, 2020 — A new study published in the Journal of Applied Psychology explores the effects of blue light-filtering glasses on sleep and work outcomes.

According to a Harvard Business Review article by Christopher M. Barnes, a conductor of the study, blue light-filtering glasses may improve employee sleep, productivity, and work outcomes, which may translate into a return on investment for companies (as the Swanwick glasses used in the study retail for $69).

“It’s difficult to quantify the value of an employee who is 8% more engaged, 17% higher in helping behavior, 12% lower in negative work behavior, and 8% higher in task performance,” writes Barnes. “However, given the expense of human capital, this is likely to be a substantial amount.”

According to EB’s 2020 Market Trends report, “As for lens technology, the sale of eyewear for use with digital devices has surged ahead of other specialty product. That’s partly because, according to ECPs surveyed, 40% of their patients are now aware of blue light issues.”
