Black Lights

Do these pose any threat to eyesight? I have noticed that my eyes usually hurt after awhile of being in a place that has them or i get a headache.

That's the pot smoke.

Commercially available black lights do emit low-frequency ultra violet wavelengths.

You can cloud your corneas and tan your retinas if you look directly at the black light source for a lengthly period of time.

You will not be harmed by the light of blacklights reflected off surfaces because the UV wavelenths are absorbed by the electrons of the surfaces and re-emitted as visible light.

What UG is telling you is that there's possibility for litigation against the black light manufacturers.

I hope we're not suggesting another means for a lawsuit. Blacklights have been around for over 30 years, and to the best of my knowledge, no one has ever been injured by one (with normal usage). All it takes is common sense when using a blacklight:frown:



That's all we need............another lawsuit -kd5-
