Description
It looks like a barely-there, crystal-clear frame — until you walk into the sun. The transparent front deepens to a cool grey while the lenses darken from clear to sunglasses-dark. Subtle indoors, striking outdoors: the most versatile pair of photochromic glasses you will own.
Key Features
- True Clear-to-Shade Transition: a fully transparent frame that shifts to soft grey in sunlight, paired with nylon lenses that go from clear to dark.
- Clear Vision Indoors: colourless frame and clear lenses mean zero colour distortion for reading, screens and indoor work.
- Built-In Sun Protection: step outside and the lenses become transition sunglasses in seconds — no clip-ons, no second pair.
- Ultra-Light 28.5 g Frame: injection acetate construction keeps the weight down while delivering a premium, glass-like look.
- Universally Flattering: a transparent frame is the most neutral accessory there is — it pairs with every outfit and suits every skin tone.
Description
Some glasses make a statement. The C2 quietly fits into every part of your life — then surprises you outdoors. Indoors it reads as light, minimal and modern: a transparent injection acetate frame with crystal-clear nylon lenses that virtually disappear against your face. Wear it on a video call, in the classroom or at the dinner table without a second thought.
Then the sun comes out. The transparent front deepens to a sophisticated translucent grey, and the lenses darken to a clean, neutral dark-grey shade. In about the time it takes to walk out the door you are wearing a completely different pair of sunglasses. At just 28.5 g, with smooth temple arms and a balanced retro round shape, the C2 is built for people who wear glasses from morning to night.
Perfect For
- All-day office wear: invisible indoors, sunglasses at lunch.
- Beach-to-boardwalk holidays: clear for photos, dark for the sun.
- Errand days: drive, shop and stroll without changing glasses.
- Minimalist packers: one frame replaces two in a carry-on.
