A metal upper rim and a nylon cord holding the lens from below, the lightest full-size frame here.
A clear plano lens with no prescription in it. Take the frame to an optician for your own lenses. Lens guide
Choose a frame size before adding it.
Half-rim means the lens is held by a rim along the top and a thin nylon cord running in a groove around the bottom edge. You see less frame and the whole thing weighs 14 g. The upper rim is titanium in the gunmetal version and a titanium core with an acetate sleeve in the mahogany.
Two honest limits. The cord stretches a little over two or three years and the lens can start to pop out; any optician replaces the cord in five minutes and we cover it under the hinge-and-coating guarantee. And a half-rim needs a lens at least 1.8 mm thick at the edge to take the groove, so very thin high-index lenses are not always possible - ask your optician before you pay for them.

Worn first. Six of us wore this frame daily for a month before it was listed. The weight and the hinge type above are what we measured, not what the supplier told us.

Measured my old pair as the fit guide said, ordered the matching size, and it sat right without a visit to the optician for bending. The weight on the page was the weight on my kitchen scales.
Second frame. The first was glazed by my optician without any fuss - she liked that the demo lens was already the right shape.
Exactly as described, including the part about the coating smudging. It does. The cloth set sorted it, but I would have liked that in bigger letters.
Look inside the temple of a pair you own. The first number is the lens width; match it to the nearest size here. If there is nothing written there, measure the width of one lens with a ruler.

| S | 47 mm | about 128 mm | under 132 mm |
| M | 50 mm | about 134 mm | 132–140 mm |
| L | 53 mm | about 140 mm | over 140 mm |
Bridge and temple length do not change between sizes on any frame here.
