2541 Glasses by Lindberg. Color: 10, 20, 25, 30, 35, 60, 70, 75, 77, 80, 85, 90, 95, GT, U12, U13, U16, U9, Size: 52, 54, 56, Bridge: 22, Temple Length: 145, Temple Design: Basic. With a narrow oval lens and ultra-thin temples, the 2541 from the LINDBERG Spirit Titanium Collection is all about low-profile charm. The clean frame is barely visible on the face, lending a whisper-light elegance. Despite its airy look, it holds securely throughout the day. A great pick for minimalist purists.
