Description
Pale, sunny yellow indoors. Fired-up red outdoors. The C6 is the most energetic pair in the 52613-2 photochromic line-up — a frame that literally changes its mood with the weather, while the clear nylon lenses darken to full sunglasses shade.
Key Features
- Yellow-to-Red Solar Shift: watch a soft light yellow frame heat up to a vivid red under UV — the most dramatic colour transition in the series.
- Double Photochromic Action: frame and nylon lenses both respond to sunlight, taking you from clear indoor glasses to dark transition sunglasses automatically.
- Instant Mood Boost: yellow frames are proven attention-grabbers and smile-makers; the red outdoor mode doubles down on confidence.
- Featherlight 28.5 g Frame: injection acetate retro-round construction that disappears on your face — until someone notices the colour.
- Festival and Street-Style Ready: built for wearers who use eyewear as the centrepiece of their look.
Description
The C6 does not whisper. It glows. Indoors you are wearing a cheerful light yellow photochromic frame — translucent, warm and unmistakably upbeat, with crystal-clear nylon lenses for undistorted everyday vision. It is a colour that photographs beautifully and lifts every neutral outfit.
Take it into the sun and the energy spikes: the pale yellow front and temples deepen into a saturated red, while the lenses darken to a true sunglasses shade. From “cute yellow glasses” to “wow, red sunglasses” in the time it takes to find your glasses case — except you will never need the case, because the transformation happens on your face. The retro round silhouette with keyhole bridge keeps the bold colours grounded in a classic, flattering shape.
Perfect For
- Festivals and concerts: a colour-changing pair belongs in the crowd.
- Summer travel and beach days: yellow in the shade, red in the sun.
- Street style and creator content: every outdoor post becomes a before-and-after.
- Gift-giving: a pair that gets an audible reaction when it changes.
