These are the bomb-diggity of eye wear!  Full UVA/UVB Protection.  They have a string to use in the stand up, or they disconnect to become two pieces for a lay down bed to eliminate any possible line across the nose.  They also come with a luxuriously silky soft bag with a string tie to keep them in.  So basically these are the Mercedes of eyewear and you need a pair.
