I don't remember the glasses themselves being described as antiques, anyway. Just that they're an antique style. Probably meant to appeal to someone's affectations for the past.
And as a wearer of glasses, I've been told more than once that when getting new glasses, it is best to get new frames as well. The stress of trying to mount new lenses in old frames can break the frames. This would be especially true for actual three hundred year old frames.
