We should encourage people to not pick up a flashlight and shine it into their eyes. Just common sense. No?
This is America (Here at least), and in THE USA, we need to put warnings on hammers that tell people that if they hit themselves in the head with with the hammer, it could cause serious injury or death.
We also put signs on restaurant doors that say "No Dogs Allowed", and then in parenthesis; (Except Seeing Eye Dogs).
I figure the world might be better off w/o the people that hit themselves in the head with a hammer due to a lack of warning not to, and that the blind guy with the seeing eye dog will not see the No Dogs Allowed sign anyway...so a note to him on the sign saying his dog's OK would not be noticed either by the blind guy, etc. If the DOG could read, fine.
So, common sense about NOT shining a flashlight into eyes might be optimistic...and could lead to more kids being blinded, and then bringing their seeing eye dogs into places where the signs say no dogs allowed, and being unable to read the warning on the hammer, or the hot coffee, etc....which is of concern as they didn't have the sense to not look into the bright flashlight beam either....and now are vulnerable to self inflicted hammer strikes and burned laps too.
