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.
