Ray-Ban Interchangables
With the straight-forward design of Ray-Ban's most popular styles, it's a wonder these hadn't come out a long, long time ago. Ray-Ban Interchangables ($230) turn the company's venerable Aviator and Caravan shades into three-in-one sets with mirrored, gradient, and polarized lenses included to go with the gunmetal or gold frames, as well as a carrying case for one extra set of lenses. Prepare to be the envy of every State Trooper you come across.
