A model of ocular and facial skin exposure to UVB is presented that combines interview histories of work activities, leisure activities, eyeglass wearing, and hat use with field and laboratory measurements of UV radiant exposure. Site-specific exposure is expressed as the product of personal ambient exposure, defined as the ambient exposure while an individual is exposed to sunlight, and factors that describe the ratio of site-specific to personal ambient exposure. Ocular exposure is further corrected by the UV attenuation of typical eyewear. The model was used to compute cumulative and yearly exposures in a population of 838 watermen who work on the Chesapeake Bay and are highly exposed to sunlight. The model was found to be predictive of conditions known to be caused by excessive sun exposure--skin elastosis, climatic droplet keratopathy, and squamous cell carcinoma--and has been useful in several epidemiological studies.
