Nina Grey Photochromic Lens Glasses – Black Square TR90 Frame

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.
