These are not at all what they seemed to be.  They are &#34;bifocals&#34; only in the sense that the lower portion is the advertised magnification while the upper section is just plain 0.00 plastic.  They were also exceedingly narrow.  The arms were stretched far out of parallel when I put them on.  Admittedly, I have a wide head but not so wide that I'm unable to buy reading glasses off the rack at the drug store.  I purchased these because I was looking for actual bifocals that would allow me to use half for reading and half for writing on my computer.  These were not even close to being adequate for this.<br /><br />I'm going to be returning them.
