STO405 — Women's Sunglasses by Tous The STO405 offers a rounded silhouette set in a metal frame, crafted for everyday wear as well as special occasions. The design blends fashion-forward flair with practical functionality, making these sunglasses a striking choice for outdoor activities. True to Tous’s ethos, the frames carry an air of approachable femininity and meticulous detail, a hallmark of the Barcelona-based brand. Sizing sits at 54-20-135: 54 mm across the lenses, a 20 mm bridge, and 135 mm temple length. A 54 mm lens width tends to flatter oval, round, and heart-shaped faces especially well. Construction-wise, the round shape evokes retro circular aesthetics, softening the overall look and lending a timeless vibe. The full-rim design defines the lens edge with a sense of solidity. Lenses provide UV400 protection, blocking 100% of UVA and UVB radiation. They come with a standard sun-filter rating suitable for general outdoor use.
