Violet Shift, Everyday Ease

Purple photochromic lenses stay clearer indoors, then darken outdoors in sunlight—built for sideline weekends and bright city walks that bounce between shade and open sky. The activated violet tint brings a style-forward pop while helping soften harsh glare when the day turns bright. In the Tortoise Round TR90 Frame round Tortoise frame, flexible TR90 keeps the feel light and easy in a medium fit. Together, it’s a statement pair that still wears effortlessly from gallery afternoons to weekend plans—and last-minute invites.

  • Lenses: Purple photochromic lenses stay clearer indoors, then darken outdoors in sunlight (UV-activated) with a bold violet tint for a standout look.
  • Frame: Tortoise Round TR90 Frame round, full-rim TR90 frame in Tortoise—warm amber tortoise look that keeps the vibe classic.
  • Build: Flexible, impact-resistant TR90 designed to feel air-light for all-day comfort.
  • Fit: Medium fit profile (50-23-148) with a 144 frame width.
  • Face Shapes: Oval, square, heart-shaped, and diamond faces.
  • Best For: Sideline weekends, bright city walks, and in-and-out days when the light keeps changing.
