Violet Shift for Changing Light

This light-adaptive purple lens stays clearer indoors, then deepens outdoors in sunlight for an easy color shift on in-and-out days. Photochromic tint is UV-activated, so it may stay lighter behind most car windshields.

Nina in Black keeps it clean with a glossy soft-square TR90 frame and adjustable metal nose pads to dial in comfort. It is an easy everyday pair from desk time to daylight errands.

  • Lenses: Purple Photochromic CR-39 lenses stay clearer indoors and deepen outdoors in sunlight (UV-activated) for changing-light comfort.
  • Frame: Nina in Black is a slim soft-square TR90 frame with a glossy finish and adjustable metal nose pads for a more secure fit.
  • Build: Lightweight full-rim build with standard hinges; flexible TR90 keeps the feel easy from morning commutes to evening plans.
  • Fit: Soft-square shape with roomier coverage that flatters round and oval faces. Nose pads help fine-tune the fit.
  • Best For: In-and-out days, doorway-to-daylight errands, patio breaks, and weekend walks.

Purple Photochromic Lens delivers a distinctive violet tone that adapts as you move through different light—clearer indoors, darker outdoors in sunshine. It's a statement tint that still feels easy to wear day to day. Photochromic tint is UV-activated, so it won't darken significantly behind most car windshields.
  • Clear indoors, darkens outdoors in sun (UV-activated)

  • Helps reduce harsh glare in bright light
  • Style-forward color that still feels easy to wear
