Eye protection from light radiation.

Abstract

It appears that green absorptive lenses are highly desirable for the purposes of shielding the eyes against light radiation from molten metal during the casting and soldering procedures. The dental laboratory technicians have experienced no after-images, less eye fatigue, and no adverse symptoms when using these lenses, as were reported previously. The lenses not only effectively protect the eyes from the injurious light wavelengths, but they also provide for enough normal (as well as individually corrected) vision to accomplish any procedure necessary in the dental laboratory. We propose that the green absorptive lenses, with individual corrections if needed, be considered for dental laboratory technicians during dental laboratory procedures when needed, such as during casting and soldering, to protect their eyes from light radiation.
