ABSTRACT
For quite some time people have been showing interest in the health aspects of the relationship between work and vision. In the past such interest was mainly orientated towards the etiology and treatment of chronic and degenerative diseases, either ocular or visual, connected to the presence in the working environment of large amounts of chemical (lead, sulfur-dioxide, solvents, etc.) and physical (ionizing radiation, UV, IR), pollutants. Consequently, medical intervention in this field has been mainly directed towards diagnosis and treatment of impairments of the visual system.
