Your Screen or Monitor
Correct placement and adjustment of the screen or external monitor can reduce eye, shoulder, and neck
fatigue. Check the following when you position the screen or external monitor.
•
Adjust the height of your screen or external monitor so that the top of the screen is at or slightly below
eye level. Your eyes should look slightly downward when viewing the middle of the screen or external
monitor.
•
Position your screen or external monitor no closer than 30 cm and no further away than 75 cm from
your eyes. The optimal distance is between 35 cm and 45 cm.
•
Rest your eyes periodically by focusing on an object at least 6 metres away. Blink often.
•
Position the screen or external monitor at a 90° angle to windows and other light sources to minimise
glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen or
external monitor.
•
If reflected light makes it hard for you to see your screen or external monitor, use an anti-glare filter.
•
Clean your screen or external monitor regularly. Use a lint-free, non-abrasive cloth and a non-alcohol,
neutral, non-abrasive cleaning solution or glass cleaner to minimise dust.
•
Adjust the screen or external monitor's brightness and contrast controls to enhance readability.
•
Use a document holder placed close to the screen or external monitor.
•
Position whatever you are looking at most of the time (the screen or reference material) directly in front
of you to minimise turning your head while you are typing.
•
Get regular eye check-ups.
Your Sound Devices
Excessive sound pressure from earphones and headphones can cause hearing loss.
•
Keep your computer's sound level low.
•
Get regular hearing check-ups.
