I purchased these glasses in May.  Honestly, I did not wear them but once or twice.  I went to put them on the other day for the 3rd time and the frame is split with the lens falling out.  What a disappointment and it is too late to return them.  I am very frustrated because I could feel my eyes relieved of stress when I put the glasses on, but apparently they are so cheaply made that they break with little effort.  I do not have a home where children or pets are running around.  The frame just plain broke.
