Improperly positioned monitors can cause stress on vertebrae and spinal discs. Position monitors so the first line of text is at eye level. Employees that wear bifocals should position their monitors lower so that they do not have to tilt their neck up to view the screen. Of course, position the monitors so they do not reflect a glare from lights or windows, and make sure that they are approximately 18 to 30 inches away from employees' eyes. Workstation equipment must also be properly adjusted to avoid injury.
Chairs are perhaps the most vital key to avoiding injuries.
Select a chair with adequate lumbar support. Employees should adjust the chair properly so that it provides this support. Many workplace injuries are caused by poorly-adjusted chairs. Keyboards should be level or even tilted slightly backwards. An angle more than 15 degrees off level strains the wrists.
