Most frames are made from bio-based acetate or lightweight metal, and the lenses are flat-pane designs that give a modern, minimalist look.

Flat lenses reduce distortion and often provide a sleek silhouette. Look for UV-400 protection and consider whether the frames have adjustable nose pads for comfort. Bio-based materials are eco-friendly and lightweight, making them good for all-day wear.

When selecting, check the bridge fit and temple length to ensure they sit securely without slipping. Grey lenses are versatile for everyday wear and pair well with most outfits.
