Clear Indoors, Grey Outdoors
Grey photochromic lenses adapt as your day moves between inside and outside: clear indoors, then a neutral grey tint outdoors in sunlight. Photochromic tint is UV-activated, so it may stay lighter behind most car windshields.
Nina in Black keeps it low-fuss with glossy soft-square TR90 and adjustable metal nose pads for fine tuning. It is an easy pair for office light, window light, and quick steps into bright sun.
- Lenses: Grey Photochromic CR-39 lenses stay clear indoors and darken outdoors in sunlight, with a neutral grey activated tint. UV-activated for changing light.
- Frame: Nina in Black is a slim soft-square TR90 frame with a glossy black finish and adjustable metal nose pads for a custom fit.
- Build: Full-rim TR90 build with standard hinges; lightweight feel that stays comfortable through long days.
- Fit: Soft-square shape adds definition for round and oval faces. Adjustable nose pads help keep it secure.
- Best For: Doorway-to-daylight commutes, walking between meetings, weekend errands, and travel days.
