Suppose one was working at an industrial site, wasn't wearing proper\neyewear, and was accidentally exposed to high-powered, artificial blue/\nUV light. He wasn't staring at the light but the light wasn't less\nthan 12 inches away from his eyes, and the exposure was for 5\nseconds.\n\nHours later,he feels some strain on his right eye ( surprisingly not\nhis left eye ). He also has headaches. The symptoms of headaches and\nstrain went away after 2 days.\n\nHe also has to blink a few times more to get clear vision for his\nright eye. ( like when you wake up in the morning and you have\nintially have foggy vision until you blink many times ) This symptom\nis still ongoing for 3 days after the exposure.\n\nIs it possible for the brief exposure to cause cataracts? Are any of\nthese symptoms of cataracts? Will it be likely that his sights ( if\ncaused by the UV ) will be normal and not suffer from permanent\ndamage? Does he require any treatment?\n\nJust wanted to have some feedback. Thanks.
