A squared-off acetate frame with a flat brow and a 52 mm lens, the heaviest frame we make.
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.
Cut from 6 mm acetate sheet rather than injection-moulded, which is why the colour goes all the way through and why it weighs 28 g. The brow is flat, the lower rim is gently rounded, and the temples are a full 5 mm wide at the hinge. It takes thick lenses without the edges showing.
Acetate loosens in heat. Leave it on a car dashboard or by a radiator and the temples will splay; a heated-and-reset by an optician brings them back, but repeatedly doing so eventually tires the hinge. Keep it out of the sun when it is not on your face.

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.
| Size | Lens width | Total frame width | Face width, temple to temple |
|---|---|---|---|
| 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.
