Avoid overreaching by keeping the input device close to the body. Position the monitor directly in front of the operator with the screen at or below eye level. One exception is bifocal wearers who may prefer a slightly lower monitor level. Monitors should have good contrast, sharp focus, and be free from flickering and glare to minimize eye strain. Position the document holder at eye level, close to the monitor.
Head sets are particularly beneficial for people who work on the phone and computer simultaneously.
Dimming overhead lights and use of a task lamp can reduce eye fatigue. Monitor shades and glare screens also reduce glare. Adjust monitor contrast and brightness for maximum personal comfort.
