Ergonomics: visual and physical

BACKGROUND

Overuse of the same muscles and ligaments while trying to adjust to static furniture or equipment over time can cause discomfort and strain the body, especially in occupational environments that require repetitive tasks. Under such conditions, the effects of even slight visual or physical discomfort are compounded, leading to decreased occupant comfort and focus.
