Sito Indi Polarized Sunglasses

Retro square polarized sunglasses built for sun-drenched days

The Sito Indi brings a larger square shape with rounded edges to the beach, the kind of retro Italian-inspired look that pairs an easy weekend with real polarized lens protection. If you have been searching for polarized sunglasses with a vintage feel, the Indi leans into that bygone-era design instead of a generic sport wrap.

What the frame and lenses are made from

The Indi frame is handmade from plant-based acetate rather than standard petroleum plastic, and it is built around CR-39 lenses, a high quality optical lens material long used for clarity and scratch resistance. The lenses are rated to a high level of UV protection at lens category 3, and the frame itself is made to Australian standards, one of the stricter sunglass safety benchmarks in the industry.

Who reaches for the Indi

This is a women's frame built for the moments between the water, not for paddling out. Pool lounging, walking the docks, brunch with friends, or just riding along in the boat, the Indi is meant to move from casual outdoor time to more social settings without looking like sport eyewear. The larger square shape gives solid coverage for bright, reflective South Florida light off water, sand, and boat decks.

Caring for a plant-based acetate frame

Store the Indi in the included protective pouch when it is not on your face, since acetate frames scratch more easily against keys or sand left loose in a bag. Rinse off salt spray or sunscreen with fresh water and a soft cloth rather than wiping dry, which can grind grit into the CR-39 lens coating. Avoid leaving the frame on a hot dashboard for long stretches, since sustained heat can soften acetate over time.

Sito's approach to eyewear

Sito builds the Indi around handmade construction and a sustainability-minded packaging choice, pairing a retro design cue with genuine attention to lens quality and frame material rather than treating the vintage look as a shortcut around performance.
