Black square sunglasses for women with dark lenses
Black square plastic sunglasses are a simple pick when you want a clean front shape with a bold frame edge. This pair uses a full frame plastic build and a balanced unisex look, so it can suit everyday outfits without feeling overdone. The frame comes in a glossy black finish, and the front has a square profile with softly rounded corners. The lenses look dark grey with a gentle fade that becomes lighter toward the bottom, which keeps the look calm rather than harsh. On the temples, you can see a small round metal accent near the outer side, plus a light cream end section that adds contrast against the black frame. Because it is a full frame design, the rims outline the lenses all the way around and give the sunglasses a strong, solid outline on the face. The plastic material keeps the frame smooth and easy to wipe clean, and the straight temples look even and streamlined from the side.
Fit and sizing
The size is 57-17-145 (Width?Bridge?Temple). A 57 mm width gives a medium front size that feels structured without being extremely wide. The 17 mm bridge is a helpful guide for how the frame may sit across the nose, while the 145 mm temples show a standard arm length for steady wear during normal day use. If you like a square shape with a comfortable, regular fit, this sizing is a good reference point when comparing other frames. These sunglasses work well for daily errands, commuting, travel days, walking, and outdoor shopping. For more shapes in this style, browse our square frame styles. Overall, these black square plastic sunglasses keep a sharp, minimal look with subtle contrast details and an everyday 57-17-145 size.
