Query: Not as advertised

These are not reading glasses, they are bifocals.They have a small area of the lens which has the visual adjustment.If you need them for working on anything that takes up your whole visual field they are useless.Furthermore, when I returned them because they were not as specified, Amazon changed my reason for return from "Not as Ordered" to "Delivered Late" and charged me for shipping.
