Task lighting is an essential type of lighting which is important in preventing eye strain. It provides focus on the task. Task lighting is different depending on what tasks are being undertaken. For different tasks, different task lights are used depending on where the focus is required.
In some cases, the background lighting can create enough light to illuminate the area where tasks are being carried out. In other cases, when task lights are used, they tend to be a more direct light on the area where the light is required.
