Robert Reuss's List: 102 Advance Ergonomics

  • Nov 22, 11

    To understand the best way to set up a computer workstation, it is helpful to understand the concept of neutral body positioning. This is a comfortable working posture in which your joints are naturally aligned.

    Maintaining good postures, such as straight wrists, elbows close to the body and head straight and in-line with the torso is often difficult because of a misalignment between the user and the computer components and accessories.

    • Remove the middle bulbs of 4-bulb fluorescent   light fixtures to reduce the brightness of the   light to levels more compatible with computer   tasks

    Although humans cannot see fluorescent lights flicker, the sensory system in some individuals can somehow detect the flicker.

    • Although humans cannot see fluorescent lights flicker, the sensory system in some individuals can somehow detect the flicker. Ever since fluorescent lighting was introduced in workplaces, there have been complaints about headaches, eye strain and general eye discomfort. These complaints have been associated with the light flicker from fluorescent lights.
    • When compared to regular fluorescent lights with magnetic ballasts, the use of high frequency electronic ballasts (20,000 Hz or higher) in fluorescent lights resulted in more than a 50% drop in complaints of eye strain and headaches.

    When placed in the wrong position it can force the operator to work in a variety of awkward positions.

    • forced working body positions significantly contribute to the operator's discomfort, and can potentially lead to work related musculoskeletal injury (WMSD). Other adverse effects of a poorly located monitor are eye irritation, blurred vision, dry burning eyes and headaches, collectively called eyestrain.
    • The sheer number of such complaints indicates that the proper position of the monitor has not received enough recognition as an important factor in the arrangement of a computer workstation.

    Computer glasses are prescription glasses that are designed to wear when doing computer work. They allow you to focus your eyes on a computer screen, which is farther away than reading material is normally held.
