Hi
 Actually it doesn't hurt your retina, it damages your
cornea. This frequency of uv doesn't penetrate very far
into the eye. This means that extra care is needed
since it isn't just a matter of looking at the light.
Any direct path from the lamp to the surface of your
eye can cause damage. Most reflected uv light is attenuated
quite a bit and is not as dangerous but one should still
design their box to avoid reflective surfaces like
aluminum. Even though 90% or so is lost, these lights
are intense. Cardboard or conductive foam has about
0% reflections. One can get an idea of the reflected
quantity by placing a piece of 'T'shirt near. It will
glow if hit by the uv.
