NOM 1E0 519-529-7212 PG. 32 THE RURAL VOICE, SEPTEMBER 1983 FARM NEWS False rumour There is no truth to the widely cir- culated reports that electrical arcs and sparks of welders can seriously damage the eyes of contact lens wearers. Dr. Betty Fretz, an optometrist in Listowel says she has been receiving questions about the false rumors several times a day, and has had pa- tients submit translations of the;e reports in three languages. These rumors were the result of two false reports of workers sup- posedly permanently blinded as a result of electrical mishaps. Many workers, teachers and safety directors have been needlessly alarmed, and should now be able to rest, assured that this particular ill need not con- cern them. Safety directors at the two com- panies involves, Duquesne Electric and United Parcel Service, both in Pittsburgh, Pa., have denied that such incidents or injuries ever occur- red to any of their employees. The false safety alert, whose source has not been determined, describes two workers who supposedly had contact lenses adhere to their corneas as a result of exposure to electrical sparks and arcs. In the first alleged instance, the worker threw an electrical switch into a closed position, producing a short- lived sparking. In the second, case, the worker supposedly flipped open his welding shield to better position the welding rod, and while doing so, inadvertantly struck the metal to be welded, producing an arc. According to the false report, the spark and arc generated microwaves that instantly dried up the fluid bet- ween the eye and the lens, causing the cornea to be bonded to the lens. The alert said the workers felt no pain and did not know the injury occurred un- til they tried to remove the lenses later. Dr. Mittelman, President of the Ontario Association of Optometrists, said the heat from a welding arc or electrical spark is not nearly intense enough to dry up the eye's tear fluid. Nor could a contact lens concentrate rays to intensify the heat. "A welder who is not wearing tinted welder's goggles when he strikes the arc will probably develop a condition called photokeratitis from exposure to the ultraviolet radiation
