You would think two pair of glasses would be the same prescription strength!
I ordered these for my wife, since she often leaves her readers at work.  They were extremely lightweight and the first pair clearly did the job.  Several days later she opened the second pair and found that they were an entirely different strength; so absolutely not usable.  To make matters worse, the non-reflective coating was defective on one of the lenses.  A spot the size of a nickle was clearly misapplied.  The lesson: check both pairs when you get them.
