Ergonomic Lighting- Monitor Contrast:

Probable Risks:

You may be affected with headaches and eye fatigue if the contrast between light and dark areas of the computer screen are high.

Feasible Solution:

1. It is recommended to use well-distributed diffuse light for your workstation (Workstation Ergonomics). The advantage of diffuse lighting is that
   • The visual field has very few spots (or glare surfaces) in the visual field, and
   • The contrasts created by the shape of objects become softer.
2. Use light, matte colors and finishes on walls and ceilings for better reflection of indirect lighting and reduce dark shadows and contrast.

Ergonomics Lighting- Glare:

Probable Risks (1)

The sources of direct light like windows and overhead lights that cause reflected light to show up on the monitor make images more difficult to see, resulting in eyestrain and fatigue.

1. The display screen should be p laced at right angles to windows and light sources. The task lightings like the desk lamp should be placed in such a way that the light does not reflect on the screen.
2. You should clean the monitor frequently by wiping with a clean and dry cloth. A layer of dust can add to glare.
3. You can help reduce the glare by using blinds or drapes on windows.
   Note: V ertical blinds work best for east/west facing windows and horizontal blinds for north/south facing windows.
4. You can attach glare filters directly to the surface of the monitor to reduce glare. Take care that these filters do not significantly decrease screen visibility. In order to redirect lighting, you can install louvers, or "egg crates" in overhead lights.
5. To reduce glare from overhead lighting, you can u se barriers or light diffusers on fixtures.

Probable Risks (2)

The users may suffer from discomfort, annoyance, or loss in visual performance and visibility due to the reflected light from polished surfaces such as keyboards.

You can paint your walls and work surfaces to limit reflection around the screen. Use a medium colored, non-reflective paint. Arrange workstations and lighting to avoid reflected glare on the display screen or surrounding surfaces.

Note: It is noticed that a few number of high-powered lamps will minimize glares than a large number of low powered lamps.

• You can slightly tilt down the monitor to prevent it from reflecting overhead light.

The computer monitor (Ergonomic Monitor) can be adjusted for dark characters on a light background. This reduces the reflection compared to the light characters on a dark background.
