UV light hazard

["Paul Mathus" <pmathus-at-learningco-dot-com> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

     Hey folks, glad to see the list back up.
     
     I was hoping someone could give me a simple explanation of why the 
     streamers from a Tesla Coil or Jacob's Ladder do not pose a UV danger 
     to your eyes.
     
     This would help me reassure my parents that my coil is  not going to 
     blind me.
     
     I assume it is because it's heavy amps in the spark, as in an arc 
     welder or sparkgap, that lead to UV emission? 
     
     thanks,
