The present work is based on the experience developed in the company autopista central in Santiago of Chile, specifically in the area of imaging (AVI) that serves as a fundamental support for the collection of vehicles using roads with tele toll system. FROM THE POPULATION?N INTERVENED: Workers in this area comprise two shifts of 7,30 hours each in where front of a flat screen at a distance average of 45 cm in the relationship vision (eyes) and screen, each operator tele should visually discriminate validity of car plates and make valid the respective collection. To perform an average of 4000 images effective and consolidated during their working day; Each image on average should take an average of 5 seconds; The visual work is very high, requiring a high psycho-physical load otherwise. A brief description of the population established in preferences and lifestyle questionnaires us sheds than: age average 30.6 30.7 ladies male stature average 150.4 cm ladies 171,9 cm male weight 60,625 Kg ladies 77,162 kg average male BMI (IND.
