Abstract

In 1998, the International Electrotechnical Commission (IEC) TC76 included a formal _condition 2 to account for the additional hazard of viewing a highly diverging beam with optical aids. However, recent analysis of ocular exposure for condition 2 revealed that the measurement criteria currently used in the IEC Standard to account for these additional hazards are overly conservative. Efforts are underway to develop better methods that address viewing a diffuse extended source and visible sources of photochemical retinal hazards.
