Lighting Lighting can enhance or hinder office operations. VDT screen glare is known to cause eye strain, headaches, loss of concentration and productivity. Unfortunately, computers often live in environments where other tasks are performed and where high illumination levels are needed. Lighting measurement is not always a straightforward process either. Unless the VDT can be given its own room, it will likely be subject to excessive ambient light levels and glare.
Windows are especially troublesome.
Occasionally, a hood will be needed on a VDT to reduce stray light and glare on the screen. Be aware, however, that many people feel uncomfortable at first in environments with this lower level of illumination. Task lighting is often the best solution. This usually offers considerable energy savings as well. New, modular office workstation systems carry this concept to an advanced degree.
