This conversation has gone places I didn't expect. Leo, that card is 
pretty cool, but for a few hundred $$ more, you can get a light meter 
(if someone is smart enough to use the card...)

Does anyone *use* any eye protection (other that not looking at the 
light, turning off the light etc) -- I mean like protective goggles, 
etc, when doing simple things like adding/removing patch cables from an 
SMF patch panel.

I get that if you *know* the gear you are using has a Class 3 laser on 
it, you should be careful... but when you are patching it into a 
building's cable plant and some schmuck is patching the last leg in for 
you (or has pulled it accidentally, etc).. um, "don't look at it" is our 
community's BCP?
