How does proper lighting increase performance?
According to The American Optometric Association, excessive overhead or ambient lighting levels reduce the apparent visual contrast on computer screens due to glare.
“Contrast (which is reduced by glare) plays an important element in visibility. Low contrast objects are difficult to see, regardless of their size. Increasing task contrast is an important means of increasing overall performance.”
The Bottom Line
Optimal task illumination levels through the use of task lighting will help improve user ergonomics, reduce operating cost and increase worker performance.
