Both intensity and quality of lighting (illumination) are important for preventing vision problems at work.  Common lighting problems include too much light, too little light, glare and shadows.  In order to see fine objects and read in poor lighting, we often use awkward body positions.  Lighting should be evenly distributed throughout the workplace and should not create glare or shadows.

Here are some tips to prevent vision problems:

POSITION work so that it is easy to see.  Use adjustable chairs, well-positioned computer monitors, adjustable work surfaces, and task lights.

USE legible source documents and computers with good image quality.

MAINTAIN adequate humidity levels to prevent dry eyes.

ENSURE regular eye examinations to avoid problems of uncorrected or improperly corrected vision.

ENCOURAGE frequent changes in body position by varying tasks.

POSITION desk with window to the side of the worker.

POSITION desk so that ceiling lights are to the sides.

ADJUST window blinds or drapes to control light levels and glare.

USE task lights to increase light levels when needed.

LOOK up and away from work frequently to rest the eyes.

DO NOT hang glossy pictures or objects in places where light will reflect into eyes.
