I don't. Unlike the old days with the UV fluorescent tubes, I use a home-made LED light. It is a modified spotlight with the LED array back slightly in the housing. This means that not only is the light emmitted from a narrow range of near-UV but it is also fairly directional.
I'm not suggesting that those who do don't or those who are considering follow my lead. If it makes you happy or you are particularly concerned then by all means get some -- they are cheap and will protect against all sorts of stuff (dirt in your eyes, bugs in your eyes etc. I just don't think it is as critical as when people used field lights that put out a broad spectrum including some shorter wavelengths.
