Input:
This product is unique in that it actually performs the functions of two products.  They are your typical Speedo Goggles and Sun Glasses.  Typical may not be the best description in that I believe Speedo makes the best swimming goggles out there.  These perform as good as my other Speedo Goggles. In addition, they are tinted so they act as sun glasses.  They are not polarized or anything like that, but they do cut down the amount of light entering your eyes which helps on those very sunny days.  In summation, great goggles!
