Overview
A crucial component to setting up your workstation is your lighting, which can be associated with vision problems (eyestrain, dry eyes, itchy/irritated eyes), health problems, and reduced work performance. Computer work can be particularly visually demanding.

Optimal Lighting For Your Work Space

1. The ambient lighting you use should be low or glare free.
Indirect or direct/indirect light fixtures provide the best lighting solutions for many offices. This kind of light fixture hangs from the ceiling and gives more even illumination.

2. The task lighting you choose can be used to provide supplemental light for paper documents.
If you do choose to use a task light to illuminate paper documents, be sure to:

Choose a low glare, asymmetric lens.

Choose an adjustable position task light and place it in a convenient position to light-colored documents without causing reflected glare in the computer screen.

Position your task light to the side of the computer screen so that the light shines on paper documents rather than the monitor screen.


3. Your light level should be appropriate for your tasks.
With too much ambient light your computer screen will look "washed out" because of veiling glare. This makes reading more difficult, and increases your chance of making reading/typing errors.

4. Use blinds or drapes to control the light from windows.

Avoid veiling glare that is caused by direct light shining on the monitor screen, washing out the images.


5. Fluorescent lighting is preferable to other types of office lighting.
Make sure your fluorescent lamp doesn't flicker.

6. All of the lamps in your light fixtures should have the same color temperature.
Split keyboards divide the keyboard into two halves, each of which points slightly outwards.‹ The outward angle lets your wrists and forearms point inward without requiring your elbows to come in as far, better conforming to the contours of your body. Conversely, thinner people may find a traditional "straight" keyboard more comfortable.

7. The lamps in your light fixtures should compliment your home office colors.
Cool white lamps will enhance blues and greens; warm white lamps will enhance yellows and reds.

8. Optimize the color of your room.
The room color can be optimized by:

Painting or papering the walls in a neutral colors

Painting ceilings white or a light color (avoid dark ceilings)

Using a neutral floor covering (carpet, wood, tile) with a low reflectance

Choosing furniture (chairs, desks, file cabinets) with low range reflectance

Choosing office technology with a neutral color and low range reflectance


Look for these common problems:

1. Inadequate lighting levels.
The area where you work is too dim or too bright, or the lighting fluctuates during the day because of bright sunlight.

2. Direct glare from light fixtures.
When you look at your computer screen, you can see bright objects reflected in the screen, such as lights, paper, or your clothes.

3. Reflected glare on computer screens.
When you look at your computer screen, you can see bright objects reflected in the screen, such as lights, paper, or your clothes.

4. Veiling glare.
When you look at your computer screen, it looks washed out because there is too much direct light falling onto the screen.

5. Harsh lighting and shadows.
The lighting shines straight down from the fixtures, making the ceiling look dim and the office look gloomy. Another sign is when the lighting causes dark shadows on the faces of others in the room
