Vision problems

Visual discomforts are frequent complaints of computer workers. Eyestrain and headaches blurred vision are the most common problems that were reported. It can also occur when your eyes start to feel tired, they may go slightly blurred, and they often get dry and itchy. Other problems include double vision, burning and dry eyes, eye fatigue, and light sensitivity. Neck shoulder and back pain can also be related to viewing the computer keyboard and/or screen. The American Optometric Association has designated this complex of problems as computer vision syndrome (CVS). 

Lighting and vision are inter-dependent. Workplace lighting and visual ability both play a significant role in work posture. Workers alter postures to get relieved from stress on the eyes. Complaints of neck, shoulder and back pain can frequently be alleviated if visual ergonomics are identified.
