For those who like dainty things, here is a Bling Singing Angel to be used as an eyeglass/Reader holder pin.  She has a halo, spread wings rhinestone gown and is holding a book of hymns.  You won't be misplacing your readers AND it won't get in the way of your regular jewelry as  a  chain would.  The Pin measures approximately 1  1/2" long x 1  1/2"wide.
