In 1984, only 25 percent of people used computers at work, and today that number is 68 percent. 1 Awareness of the effects of computer monitors and other similar terminals are necessary to ensure a healthy workplace. Vision problems; fatigue; eye strain; and neck, back, arm, and muscle pain are common for frequent users of VDTs. OSHA recommands taking a break after every hour on a computer screen and reducing glare on screens. Proper posture and seat adjustment also limits the amount of injuries due to VDTs.
