CRITICAL DESIGN ISSUES:
Direct Glare: Visible lamps and bright lenses can cause glare, leading to
eyestrain and eye fatigue.
Luminances of Room Surfaces: Lighting the walls and the ceiling improves
the perception of brightness in the space. It also reduces excessive
contrast between surfaces that are in an occupant's field of view.
Reflected Glare: Bright lamps and lenses can be reflected in polished room
surfaces, computer screens, and glossy printed tasks. These reflections
reduce the contrast of tasks making reading extremely difficult. Shielding or
diffusing lamps and specifying matte finishes where appropriate can
improve the visual quality of the space and avoid reflected glare. Locate
