| Outline of Final Research Achievements |
Ocular ultraviolet radiation (OUV) exposure doses, measured using mannequins with Western (adult) and Eastern (child) faces, were compared with those using a mannequin with an Eastern (adult) face. In Western, the 12 h circadian change in OUV differed from that in Eastern, with OUV exposure dose almost half of that in Eastern. The Western sculpted features provided shade around the eyes even at low solar altitudes. The effects of sunglasses and even thin rimmed glasses in Western were greater than in Eastern. Compared with Eastern adults in Eastern children with smaller facial skeletons, glasses provided greater protection against UV. Glasses are extremely useful in preventing UV exposure compared to a hat, which provided little to no protection, under highly reflective conditions.
