beau-tastrophy

OK, now I'm scared.  I have been wondering why neon nail polish is so hard to find outside of salons (can't even find it on Essie's own site), and I just read that there are safety risks associated with them.  What?!  Like, I might blind myself with the neon-ness and step off the corner into oncoming traffic?  I need more specifics.  Where's the beauty doctor when I need her?
