The Index Havana | Blue Light Optical Frames | TR90 Round Tortoiseshell Eyeglasses

The Index — Havana

Classic tortoiseshell patterning on modern TR90. The mottled amber-and-brown finish reads vintage from a distance, but the weight and flex tell a different story—this is not your grandfather’s acetate. Clear blue-light filtering lenses keep the look functional for digital workdays.
