Visual comfort test (VCT)
Developed by Bo Persson, completed by Monica Säter at Jonkoping University.
The VCT was developed by Dr. Bo Persson at KTH in Sweden. It was used to measure the preferred level of light at the working table. Bo Persson did the test with a white paper on a white table three times. Then he did the same procedure three times with a white paper on a black table. The test was completed in 2006 by M. Säter to be used for measurement of both the level of light at the working table and for the preferred complementary level of ambient light. A white paper is placed on a black table. The test starts in the room which is dark and the level of light is taken up to maximum, down again, until the subject recognises their individual level of light experienced as visually comfortable. The preferred level of light is measured as horizontal (the table) and vertical (ambient light) illumination with a light meter. Then, the level of light for the working table is kept and the ambient light is added. The level of ambient light is taken up to maximum and then down until the most visually comfortable combination of level of light at the working table and for the ambient light is found by the individual subject. The procedure is done three times and the third measurement is counted. The VCT test was used in the same way in Studies 1, 2, 3, 4 and 5.

Lighting control: PCA/49. Light source 80-3950 Lux. Working light gives 0 (80)-3950 Lux on the working table and 0 (10)-120 to the Ambient light. Ambient light gives 0 (10) – 550 Lux on the working table and to the Ambient light 0 (30)-1800 Lux. Total on the Working table 0(90)-4500 Lux. Total Ambient light 0(40)-1930 Lux.
The visual comfort test was used in Studies 1, 2, 3, 4 and 5.
