These are very nice. Easily and firmly clip to your prescription glasses. Flip up out of the way when indoors and very decently priced. They shipped quickly and came in a nice plastic case. Much cheaper than buying prescription glasses with tint and if you do damage these they can be replaced without breaking the bank. I never liked the tinted photo grey type tint built into lenses as they take a while to change back when you go indoors and won't darken in a vehicle. I can't comment on the polarization yet but i am sure they will be great when I go fly fishing in the streams for knocking out the glare.
