Since these are non-prescription lenses, you can use them as is without replacing the lenses. Unlike regular Ray-Ban models, these are Asian fit, with a higher nose bridge and slightly wider temples to better fit Japanese people. These are the newer 2140F type Wayfarers, not the older 2140A type. They are polarized, so they are also great for outdoor activities such as driving, golf, and fishing.
