The SR4068 is built as a square-shaped frame in a full plastic construction, front and temples alike, sized at a 50mm eye with 140mm temples for a fit that runs medium to slightly roomy. The polycarbonate lens carries full UV400 coverage, and this style is offered with a broad spread of tints, from a classic G15 green or brown through gradients, mirrored finishes, and a light-reactive photochromic option.

In black, the square plastic front reads as a neutral, do-it-all shade that doesn't pull warm or cool, so it sits under practically anything without competing with an outfit. There's no tortoiseshell pattern or metallic fleck to catch the light here, just a flat, consistent color that looks the same whether you pair it with a suit or a t-shirt.
