RESUMO
In order to evaluate their common beliefs in the field of ocular health, an exploratory survey was carried out among 122 professionals belonging to different ranks and specialty areas of the University of Campinas Clinical Hospital (UNICAMP-CH), São Paulo, Brazil. The non-structured questionnaire used asked about common ophthalmologic problems as well as the presence of popular myths about ocular health, such as: 'cure' of visual problems by the use of glasses; reading under insufficient lighting or watching TV too much close to the apparatus is harmful; consequences from the intensive use of the eyes; or special food being needed for better vision. The results indicated the existence of various misconceptions, even among health professionals, such as: belief in the cure of refractive problems by the use of glasses (40.0%); or damage to vision due to insufficient lighting, watching TV too much close to the apparatus or from the intensive use of the eyes (86.7%). Among the professionals performing activities within the ophthalmology department, 62.5% admitted believing in visual damage as a result of conditions such as those mentioned above and 37.5% stated that reading in a moving vehicle is detrimental to vision. From these data, one is entitled to conclude that misconceptions continue to be present, even among professionals in the health area; this indicates that educational programs in ocular health should be provided, especially for individuals working within a hospital ophthalmological service.
