Many operations managers and business owners are surprised to learn how much lighting can impact workplace productivity. A professional paper on business lighting from the American Society of Interior Designers, in partnership with 3M, Cooper Lighting, DuPont, Haworth and Masland Carpet, says that there are more than 57 million visual display terminals (VDTs) in US-based offices, and that the average worker VDT user “loses 62.5 hours of on-the-job time every year due to eye strain.” The culprit for this epidemic of eye-strained workers? Overlit office spaces. That’s right. The standard American office is too bright, and it’s bad for eyes, and for productivity. Here are some thing to consider, should you seek to make some different lighting decisions in the new year.
