|Abstract:||Blue light is emitted from a variety of light sources and can damage the retinal photoreceptor cells, potentially exacerbating age-related macular degeneration. A widening array of bright energy‐efficient sources are available, particularly white LED lamps. However, few systematic occupational health studies of blue light exposure and effects have been carried out. Assessment of blue light exposure in the occupational visual field (OVF) is complex and most hygienists are unfamiliar with the methodological issues. This exploratory study briefly examines published work on occupational blue light exposure and describes a methodology for a workplace case scenario. A narrative literature review was undertaken using a hazard/exposure/control framework. Worker and public exposure to blue light in a nail salon setting were explored, in order to understand the various exposure factors, including directionality. Worst case and typical situations were considered. Integrated effective spectral radiances from the nail resin curing lamp in the occupational visual field were recorded with a spectroradiometer, modified with a customised imaging attachment. This preliminary review indicates that most previous exposure studies have been screening in nature, based on source characteristics and simple task assessment. What is required now is the gathering of robust exposure data that will support future epidemiology and risk communication. A key consideration is the initial determination of the OVF, and whether or not blue light is present in a significant region of the field, for how long and at what radiance.|
