Here’s a tip, if you are visiting an ER and you see a “blue light” pointed up at the ceiling, don’t climb up there and look into it. It will quickly burn your cornea like a welder.

I'll never forget the first caution that I had ever seen in the read file in our shop overseas around 1979 against wearing soft contact lenses and looking at a wedding torch. It said the guy tried to remove his contact lens and his cornea was removed with it.   Yikes!
