Abstract


The principles of the field of ergonomics applied and used in various studies of behavior assessment in comfort as well as in opportunity studies to identify causes of manifestation of musculoskeletal dysfunctions are increasingly developed to create effective and safe mechanisms of analysis for specialists in the field. Thus, the authors of this paper intend to analyze, in relation to the criteria highlighted in various studies, the opportunity to use one or another of the ergonomic methods in assessing the influence of the human body posture on the level of visual comfort for computer users and progressive ophthalmic lens wearers. In the first part of the paper, some general aspects are reviewed so that in the second part to identify the useful set of ergonomic methods for this combined field - posture and sensory systems. In the third part of the paper, the authors present a case study for a subject, a carrier of progressive ophthalmic lenses and performing computer activity, to identify the most effective, complete and useful method of assessing comfort. The end of the paper presents the results and conclusions from the analysis.
