When I've used these, we put cardboard over the majority of the lamp  
(not touching the bulb of course), with a small rectangular slit about  

an inch long and 1/4" wide.  I doubt splash goggles are doing much to  

protect against any UV, but
reducing the amount of light entering the eye should help.
