Working at home usually involves two kinds of tasks that pose
different lighting problems: computer tasks and paper tasks.
Computer Screen: self-illuminated and if too much external light hits it, the contrast between the letters and background is reduced and seeing becomes more difficult. Prolonged work results in fatigue.
Avoid these reflections of a window or ceiling fixture by orienting the screen at the right angles so that no bright objects are reflected on it.
General Lighting: to balance the brightness in the field of view install a center ceiling fixture or a standing lamp. (Suggested illuminance= 10-20 f.c.)
Paper Tasks: in order to avoid reflections of light, the space should be illuminated from either side rather than in front of the task.
Lighting for prolonged reading is often best provided by ceiling mounted fluorescent placed slightly behind or at either side of the desk.
Local task lighting should be placed at the side, rather than in front of the task. The illuminance on the task should be 20-50 f.c.
