I thought all the glowing reviews must be fake, but now that I have them, maybe not.

These are the best of the inexpenisve bifocal sunglasses I have had (a few pairs now).  They seem to be well made and pretty sturdy.  The lenses are dark enough (many aren't), but the bifocal portion isn't darker than the rest (which ruined all the others for me, making it hard to see a device screen in sunlight.  They're polarized.  They're crystal clear.  They make my eyes feel better than any other pair I've tried.

If there's one tiny issue- it's that the lenses are tall, and the bifocal portion doesn't come up quite far enough for my tastes.  So I have to look a little lower than I'd prefer.  It's not a problem and I will soon be used to it.  So glad I got these.

I'd buy these again if they hold up as expected.
