The glasses are not too bad, not too good, so I am giving it three stars. The glasses are polarized to a small percentage, but not fully polarized. If you take the lens and turn it 90 degress while looking at your phone there is a very very slight change, not like true polarized glasses which could block upto 90% of the screen. The frames feel like what you would expect for $20 glasses a bit cheap and plastic. I would say that these glasses are worth $20 but your not getting any special deal, I would say that is the max value I would pay for these glasses.

Would I buy another pair of these probably not, but I am also not disapointed about this purchase. These will make good beach glasses, but if you are looking for true polarized glasses you will not be happy.
