 I see people talking about looking into a UV light source. If you are
worried about the internals of your eye, don't worry. The cornea
will absorb the UV for you. Then, you may need cornea surgery
to replace your damaged cornea. It doesn't matter if you are looking
directly into a UV light source, it is just if there is a direct line
between your eye and the UV source.
 People don't understand microwave ovens either. It isn't looking
into the microwave that is the problem, it is getting your eyes
close to a leaky microwave seal. You can look into a microwave
oven as much as you like as long as you don't get too close.
With microwaves it is the inside of the eye that is damaged.
 As was pointed out, the instructions didn't mention electrical
shock either. As I stated before, it is the temperature that creates
the UV. If it looks blue-white, it is most likely producing UV as
well. If it is yellow or orange, it is most likely not.
 Also remember that little UV is reflected from surfaces.
