I read this thread this afternoon before work and thought about blacklights throughout the day. Then I unexpectedly went bowling with a bunch of friends, and it was cosmic bowling night(black lights and disco balls
) Of course, the pair of jeans I grabbed had a stain on them right below the left pocket, which isn't the best place to have a stain like that... I'm not sure if anybody noticed though
. And the topic came up, If you had blacklights in your room and used them as a light source, would it cause any harm to your eyes after a while? If the blacklights were the
only source of light in the room, besides a TV or computer monitor or LEDs.
