Black square sunglasses green lens men are back  and this chunky pair does the combination better than most. The frame is jet black, high-gloss, and seriously thick. Sharp square corners and a wide top bar give it an architectural look that stops people mid-scroll. That notched cutout bridge is the detail that sets this pair apart from every standard black frame on the market. The temples match  fully black, no two-tone, no distraction. Dark forest green lenses sit flat inside the frame and deliver just enough contrast to make the all-black build feel intentional rather than plain.
