These seem well built although I have only had them a day. The lens does help quite a bit with the sun without being too dark in shaded areas. They look decent as well, but the lens is much taller than the picture shows.

I prefer shorter lenses and would not have bought these if the pictures were accurate. I even tried to look at them from the same angle it was taken and took normal camera distortion into account but it still looks much taller.. those pictures were definitely intentionally altered to make the glasses look better than the real ones do. And I looked on Ray-Ban's website and their picture looks accurate.

This is what they actually look like. If you like that look buy them, but don't go by Amazon's pictures.

Edit: Amazon apparently edited out my link, but look up the glasses on Ray-Ban's website. Also I have noticed that if light comes in from the sides and hits the back of the lens you get a sort of blue glare and everything gets muddy looking. Considering there is a giant source of light directly above you in the middle of the day this means walking around on a sunny day these are not a good choice. They are great for driving though. It is also any direct light at all.. I get the blue glare from dim indoor fluorescent lights as well.
