  • "First pair a success!"

    This is my first pair of glasses and I was nervous buying on line without trying them first! Thankfully I had a pretty good idea what measurements I wanted and knew I really wanted a warm tortoise tone! I was so happy when I received them because I was getting nervous waiting for them to come, but they fit great! Light weight and comfortable!

  • "Great large, lightweight frame"

    Shipped fast, fits perfectly. The lenses themselves are larger than I expected, which is great because I was trying to buy a bigger frame so I could have a larger clear field of view. Side pieces are metal, lens frame is sturdy plastic (but not so sturdy that I'd suggest bending it or subjecting it to heavy impacts). I was a bit iffy about the studs on either side, but now that I'm wearing the glasses I'm finding that I like the look. Great frames, overall.

  • "Stylish, sturdy and light"

    These frames have a thicker look without the heft. They are stylish but also sturdy without feeling heavy. They rest comfortably on the face and are large frames for wider faces.
