Bought these for my wife as they are advertised as cycling glasses, and they are poorly suited for this.  The top brim of the frame is clear so when sunlight hits it the frame illuminates in front of your eyes.  This is the opposite of what you want from a pair of glasses.  This is my biggest gripe.  They also do not rise up tall enough to the eyebrows to be adequate cycling glasses as a large portion of time is spent looking up when on a bike due to the seating position.  You end up looking over the top of the glasses, and the top of the glasses are glowing with sunlight.<br /><br />As others have noted these fit very small, but this was not really an issue for my wife, I don't have head measurements but I would say hers probably on the small side of average and the glasses fit snug.<br /><br />The quality of materials make the glasses seem like about a $20 pair but with the other lenses and case I don't feel I was ripped off at around $50.<br /><br />The bottom line is these are poorly designed for function though they look nice.  Wouldn't but these again.
