Glare and loss of contrast caused by reflections from luminous objects (e.g. on glossy paper or computer screens). In general, reflections lead to reduced contrast perception, which hinders character recognition on printed paper, for example. Reflected glare can be avoided or reduced by the following means:

  • Careful planning of the relative positions of luminaires and workstations

  • The use of luminaires with an appropriate luminance limit angle to avoid reflections in the working surface or object

  • The use of matt, diffuse or reflection-reduced surfaces at the workstation

  • Diffuse light control with systems offering a high proportion of indirect light or vertical illuminance
