I bought a pair of these for use outdoors in the Florida sun when doing chores in the yard.  It's critical for long-term eye health to use polarized sunglsses down here.  The fit is great, the glasses are light, the lenses clear, and the price is right. Others have complained about how easily the lenses scratch.  This is a normal risk with this type of lens-regardless of the manufacturer.  You can't just try to rub the lenses clean with a paper towel or other abrasive material, and you have to try to protect the lenses when storing the glasses between uses.

At this price, you could own and throw away five pairs for roughly the cost of one expensive pair of sunglasses that will end up having scratched lenses also.  Buy the five pair and learn how to protect them.
