What lighting should you use in your workspace?

Proper lighting is one of the key elements of a productive and healthy workspace. Eye health, attention span and general mood are directly linked to the quality of light. So, what type of lighting should you choose for your workspace?

Natural light should be the first choice. If possible, position your desk near a window where it receives daylight. Daylight reduces eye strain and makes it easier to concentrate. However, strong, direct sunlight can cause reflections and uncomfortable glare, so it should be controlled with curtains or blinds.

When natural light is insufficient, artificial lighting is needed. White or daylight-coloured light (5000–6500 Kelvin) should be used in workspaces. This light colour supports mental alertness and reduces distraction.

The direction and position of the light are just as important as its colour. If you use a desk lamp, the light should come from the left if you are right-handed, and from the right if you are left-handed, to avoid casting shadows. Indirect lighting is preferable, as light shining directly at eye level can cause glare and discomfort.

For those who work at a screen, screen brightness should be balanced with the surrounding light. Looking at a bright screen in a dark room increases eye strain. If your eyes burn or sting in the evenings, you can also visit the Dry Eye Treatment page.
