Controlling solar glare

A satisfactory working environment is primarily a delicate balance of ergonomics, acoustics, interior and industrial design, maintenance, and illumination. The most frequently complained about source of irritation, stress, headaches and eye strain is quoted as being the quality of natural and artificial lighting; it seems that we will withstand deficiencies in all other factors that make up the physical environment without complaint but are far less tolerant of poor lighting quality and, in particular, glare. The eye can adjust to a wide range of lighting levels without causing discomfort. We can quickly adjust to variations in lighting level and, indeed, find some contrast in lighting stimulating. Glare, however, cannot be accommodated without strain.
