| Abstract |
A description of typical workplaces with optical aids is presented. Basic knowledge of optical problems is reviewed. Advice is given for the use of optical aids for the organisation of workplaces and for the user. Optical and mechanical ratings of magnifiers and microscopes are listed. Posture and movement during work were recorded by using photographic and electroacoustical methods. Subjective complaints were compiled from a questionnaire. Field studies were complemented by laboratory analyses. Instrument myopia, strabismus fault, head postures at the microscope and the illumination in the field of view were investigated. Recommendations for users and producers are given in order to achieve minimal strain and optimal performance by users of optical aids. |
