Description
Step outside and watch them change. These photochromic glasses start as a subtle, everyday light grey frame with clear lenses — and turn into deep charcoal transition sunglasses the moment sunlight hits. No swapping, no second pair in your bag: one frame keeps up with your whole day.
Key Features
- 2-in-1 Photochromic Design: the frame fades from light grey to dark grey and the nylon lenses shift from clear to dark grey outdoors — one pair works as indoor glasses and sunglasses.
- Fast, Even Transition: advanced photochromic molecules respond within seconds of UV exposure and fade back just as naturally indoors.
- Featherlight Comfort: a lightweight injection acetate frame weighing only 28.5 g, comfortable enough to wear from morning to night.
- Sun Protection On Demand: lenses darken outdoors to shield your eyes, then return to clear for screens, reading and night driving.
- Unisex Retro Round Style: a vintage-inspired round silhouette with a keyhole bridge that flatters most face shapes, for men and women.
Description
This is the pair that ends the “glasses or sunglasses?” debate for good. Indoors you get a clean, understated light grey frame with crystal-clear nylon lenses — ideal for reading, screens and office life. Step into the sun and both frame and lenses respond: the front shifts toward a sophisticated charcoal while the lenses deepen to a true dark-grey sunglasses shade. The change starts in seconds and reverses just as naturally once you are back inside.
The frame is moulded from lightweight injection acetate — durable, smooth to the touch and comfortable enough to forget you are wearing it. Balanced 28.5 g weight and a retro round shape make it a genuine all-day frame, not just a fashion accessory.
Perfect For
- Daily commute: clear lenses on the train, dark shades on the street.
- Driving: less squinting at glare through the windscreen.
- Desk-to-terrace days: one pair from the office to daylight.
- Travel: less to pack, more to enjoy.
