Abstract(s)
Atualmente a abundância de dispositivos eletrónico-digitais que existe é enorme. Refere-se não só a aparelhos fixos, mas também aos que se podem transportar e usufruir dos seus serviços em qualquer sítio e a qualquer momento. Com o evoluir destes e com a necessidade cada vez maior de os usar nas diversas tarefas diárias, vários problemas começaram a surgir nos utilizadores. Um dos mais comuns foi a síndrome do olhar no computador (SOC).
Esta apareceu fruto da evolução da tecnologia de display que obriga a uma maior exigência visual por parte do utilizador, contrariamente ao grau de exigência dos contornos bem definidos da tinta nas folhas de papel e dos tamanhos de letra e contrastes adequados utilizados nestas. A SOC pode ser definida com base na sintomatologia, tanto ao perto como ao longe, causada direta ou indiretamente pelo sistema visual, e/ou não visual. Estes sintomas resultam da exposição prolongada a aparelhos eletrónico-digitais em posições e condições incorretas e podem até impedir o utilizador de concluir a sua tarefa.
Os sintomas que estão associados a esta síndrome podem ser divididos em quatro grupos: sintomas gerais, sintomas visuais, sintomas oculares e sintomas musculosqueléticos. Por sua vez, também os fatores responsáveis por estas queixas estão divididos em categorias: erro refrativo, resposta oculomotora inapropriada, olho seco e ergonomia.
O presente estudo permitiu concluir que os grupos de sintomas mais demonstrados pela amostra foram sintomas oculares (dor ou cansaço ocular) e sintomas musculosqueléticos (dor de costas, de pescoço e de ombros). Averiguou-se também que, a nível ergonómico, a maioria destes indivíduos trabalham de forma incorreta. Relativamente aos testes optométricos encontraram-se vários elementos com valores de amplitude de acomodação, vergência fusional negativa e vergência fusional positiva fora da norma. Por fim foi ainda possível afirmar que as entidades do género feminino têm maior tendência para percecionar sintomas relacionados com a SOC.
Currently the abundance of digital-electronic devices is quite large. It is referred not only the fixed ones, but also those which can be carried and you can make use of their services anywhere and anytime. With this evolution and with the ever increasing need to use them in varied daily tasks, several problems began to emerge in users. One of the most common problem is the computer vision syndrome. This appeared due to the result of the evolution of display technology that requires a higher visual demand by the user, contrary to the requirement of well defined ink outlines of sheets of paper and those font sizes and appropriate contrasts. The computer vision syndrome can be defined based on symptomatology, both near and distance, caused directly or indirectly by the visual system and/or non-visual. These symptoms result from prolonged electronic-digital devices use with incorrect positions and conditions and can even block the accomplishing of the task. The symptoms associated with this syndrome can be divided into four groups: general symptoms, visual symptoms, ocular symptoms and musculoskeletal symptoms. In turn, also the factors responsible for these complaints are divided into categories: refractive error, inappropriate oculomotor response, dry eye and ergonomics. The present study concluded that the groups of symptoms most demonstrated by the sample were ocular symptoms (eye pain or eyestrain) and musculoskeletal symptoms (back, neck and shoulders pain). It was also found that, at ergonomics, these individuals mostly work not only with an incorrect distance from the eyes to center of the screen and to the keyboard and angle formed by the eyes line level and by the eyes line to the center of the screen, but they also use electronic-digital devices during a too long period of time. For optometric tests several elements with outside standard values of amplitude of accommodation, negative fusional vergence and positive fusional vergence were been found. Finally, it was still possible to say that females are more likely to get symptoms related to CVS.
