  • Pretty good
Color: Matte Black on Silver/Demo Lens Lens Width: 54 Millimeters
Minor manufacturing defects like uneven finish. But otherwise a great frame.

  • Just Right Size Color and Weight
Color: Beige on Copper/Demo Lens Lens Width: 54 Millimeters
This is my second pair of this frame (husband sat on first pair) after two years using same lenses. Like Goldilocks’ porridge, they’re not to big or heavy for my small frame face; but big enough to accommodate trifocals and strong enough to wrestle with the grandkids. Best pair I’ve had in decades. Original lenses fit right in them. I hope to not need to change Rx If they can’t be found a few years from now. ... show more

  • Great Glasses
Color: Matte Black on Silver/Demo Lens Lens Width: 54 Millimeters
I had the exact same kind of glasses in a different color but they broke recently, so I bought these for a replacement. I really like the style and size of these glasses, but I know I have to be carefully not to do rough activities with these.
