Knowledge of sunlight effects on the eyes and protective behaviors in the general community.

The knowledge of sunlight effects on the eyes and protective behaviors was assessed in the general community of Brisbane, Australia. Five hundred people were systematically sampled and surveyed via a telephone questionnaire. Of the participants, 279 (56%) were female and 258 (52%) were aged 40 years or less. Levels of knowledge were found to be lower in the older subjects, those with dark complexions and outdoor workers. Most were unaware of specific ultraviolet light related eye diseases such as cataract, pterygium and eye cancer. Three hundred and ninety (78%) wore sunglasses > 10% of the time while outdoors during the day; the most common reasons for wearing included protection from glare in 254 (65%) and driving in 60 (15%). Ninety-six (19%) never wore sunglasses, the most common reasons being inconvenience in 16 (17%), thought unnecessary in 16 (17%) and uncomfortable in 13 (14%). Promotion of sun protection to prevent ultraviolet light related diseases should include information on the eye. This information is important for establishing preventative behaviors and the selection of optimal eye protective measures.
