Lighting should not produce glare. Glare and shadows may be avoided by,
a) shielding or shading light sources;
b) use of indirect lighting;
c) appropriate location of light source in relation to the direction of vision and to the object that is to be observed;
d) up lighters, with light sources at floor or low level, should not be used;
e) avoidance of windows at the end of corridors;
f) avoidance of light sources against dark surfaces by choosing light colours for ceilings or walls; and
g) avoidance of abrupt transitions from light to dark spaces. Indoor and outdoor lighting around the doorway should be suitably adjusted to prevent dazzle when entering or leaving the building.
NOTE — Due to the increase of optical scatter in the eye, the effects of glare are exacerbated for elderly people and for
individuals with some types of vision impairments (for example cataracts, corneal edema, and vitreous opacities). Glare can cause discomfort and interfere with task performance by decreasing the perceived contrast in visual displays (that is disability glare).
The provisions given in Part 8 ‘Building services, Section 1 Lighting and Natural Ventilation’ of the Code in respect of glare shall also be complied with.
