Black rounded square sunglasses are a good match if you want a softer shape than a sharp rectangle, but still like a structured front. This pair comes in a full frame plastic build with dark grey gradient lenses, giving an easy everyday look that works with casual wear and simple outfits.

The front shape reads as a rounded square: the corners are softened, and the top line has a gentle curve instead of a flat edge. The frame is mainly black, but you can also see small warm brown flecks along parts of the frame and temples, creating a subtle tortoise-style touch without turning the whole pair into a patterned look. The lenses appear grey with a smooth fade, darker at the top and lighter toward the bottom.

The full frame design outlines the lenses all the way around, so the sunglasses keep a firm, finished shape. The plastic surface looks smooth and easy to wipe clean, and the temples are slim and straight, keeping the side view neat and lightweight in appearance.

Fit and size guide

The listed size is 57-17-145 (Width–Bridge–Temple). A 57 mm width gives a wider front measurement, which can feel more roomy across the face. The 17 mm bridge helps indicate how the sunglasses may sit across the nose, and the 145 mm temple length is a common arm size that supports a steady fit behind the ears. If you want a front that feels a bit wider without going oversized, these measurements are a useful guide.

Overall, these black rounded square sunglasses keep a clean shape with a soft gradient lens look and a practical 57-17-145 size for everyday use.
