Computer Workstation Suggestions
Many vision problems can be alleviated simply by making changes, when possible, in the workstation. This checklist may guide you in evaluating vision-affecting conditions where you work.
- Keyboard, screen and copy should, ideally, be at equal distances from the eyes.
- Computer screens should be slightly below eye level (about 10-20 degrees). Copy should be at the same level as the screen.
- Locate keyboard so wrist and lower arm are parallel to the floor or angled slightly downward.
- Chairs should provide proper back support and be adjustable without tools by the operator.
- Adjust chair height so feet are flat on the floor with thighs parallel to the floor.
- Adjust the worktable so legs and knees clear its underside.
- Screen brightness and contrast should be adjusted by the operator for a maximum viewing comfort.
- Each workstation should have an adjustable, shaded copy lamp that can be aimed by the operator without causing screen reflections or direct glare into The eyes.
- Eliminate glare and screen reflections by moving or tilting the screen. Overhead lights may need baffles. Try not to face toward windows or bright light sources.
- Operators should face into an open space beyond the computer screen.
- Clean computer screen regularly; it attracts and accumulates dust.
- Adjust screen focus and image alignment frequently to reduce visual stress. Vision and performance are enhanced by taking a short break(15 minutes) every two hours. Demanding computer workloads usually require a short change from work each hour.Stop every 15 minutes to look up and away from the computer to focus on a distant object.
