Returned mine after only a few days as I really felt that the lenses didn't come close to blocking enough light.  Kept switching back and forth between several other pairs that I owned just to compare and the Headings were the only one's in which I still felt a need to squint a little.  I really liked the style and considered buying after market lenses to swap out the one's they came with, but decided that for how expensive the glasses were up front that it just wasn't worth the additional costs.<br /><br />I had the brown frame / brown polarized lens combo, but have read similar reviews with the other lenses so I wouldn't think there's too much a difference if others notice it as well.  Side note, I do live in Colorado which is very sunny, so if you live in an overcast area like the MidWest, the lenses may not be as much an issue.
