| VDUs AND VISION
To see clearly and comfortably on the VDU requires an unconscious effort. To accomplish this task several muscles are involved and the image needs to be sharp within the eyes.
The most common complaints made by VDU operators are headaches, blurred vision for either near or far viewing distances, itching or burring eyes, eye fatigue, flickering sensations, double vision, slow refocus and frequent loosing the place when moving eyes from printed material to the screen, and difficulty seeing distant objects clearly after prolonged VDU use. These complaints or symptoms are commonly called eye strain.
Rest breaks are important because VDU operators often require intense concentration. Work with screen-based equipment should be interspersed with other tasks. Alternately, glancing away from the screen for a second or two every few minutes will make work with VDU’s more comfortable.
Vision problems that usually are not usually noticed often trouble VDU operators. This is because VDU work imposes greater visual demands than traditional office work. It is likely that previously unnoticed vision disorders are one of the most common reasons for vision-related complaints by VDU operators.
