I want to buy sunglasses for my uncle who is a trucker. Do you know which lens tint color will suit trucker? I heard of that the polarized sunglasses are good for drivers, if it is true? If I buy them from the online stores, do you know the average price? Thanks a lot!

Yes, the polarized sunglasses in gray, brown or amber color are good for driving. At the professional online prescription glasses store PrescriptionGlassesOnline.net, you can get the cheap polarized sunglasses starting from USD47.90. Hope the information will be useful for you.
