My teenage daughter needed retro glasses for her role in a high school musical.  After doing some shopping, these were exactly the time frame (1960's) we were looking for.  When they arrived it was obvious these glasses are for costume and dress up purposes and not to be considered for actual optical use.  We had to remove the lenses because they had a very bad glare that made it hard for my daughter to see out of them (plastic lenses).  The asking price I consider to be in the right range for this type of "costume" type accessory.
