I bought a pair of Ray-Ban aviators with polarized lenses while on a recent trip.  These are classic style and certainly the lenses are of excellent quality.  However, there is a problem with all of the metal wire aviator style frames.  They will easily lose their shape and that will cause the lenses to fall out.  Trying to get some help on how to fix this from Ray-Ban's customer service department is impossible.  They simply won't give out any information, unless you first send in your glasses via insured and certified postal delivery.  The closest I came to getting any helpful information after re-phrasing my question was the costs of repair could range from $60 to $80 for the frames and $40 for the lenses.  I won't buy any more Ray-Bans.  They're already quite expensive.
