Ran into a friend the other day and the first thing he said was, "Man, those are some big sunglasses!" Yes indeed, the Lewis are really big and I love 'em. If you are looking for sleek shades, keep on looking. If you are looking for maximum sun protection then these are it. The frames are really big, blocking peripheral light like a champ. They are pretty light for their size (though not as light as my Kaenon Jettys which share a similar design but with a slightly more streamlined frame), and… Full review
Have owned 5 pairs of Kaenons (Jetty, Lewi, Klay, UPD, and Hard Kore) and the Jettys are my all around favorites.

Have the Kaenon Hard Kore with the Y35 yellow lenses and like them pretty well. They're lightweight for the size and are pretty big, offering a lot of coverage — these are not sleek by any means.

You can also get them in the copper and gray lenses if you want darker. Kaenon's polarization is excellent (the best I've found) and their lenses are really clear… Full review
