Polarized Sunglasses Built From Eco-Friendly Acetate
The Sito Diamond Polarized Sunglasses pair a cat eye inspired silhouette with real function, using polarized, category 3 lenses to cut glare on bright days. The frame is made from plant-based acetate crafted from natural wood pulp and cotton seeds, so the same soft, flattering angles that make this style work for everyday wear also come from a more sustainable material.

Who It Is For
This is a pair built for daily wear as much as it is for the beach or the boat, a single set of sunglasses that carries you from a morning session to running errands afterward. The polarized, category 3 lenses handle strong, direct sun, which makes them a solid choice for South Florida's year-round glare.
Fit, Wear, and Care
Because the optical frame is prescription-ready, it can be fitted with prescription lenses if needed, a useful option for anyone who normally wears corrective glasses. Store the sunglasses in the included microfiber bag when not in use, and use that same bag to wipe down the acetate frame and lenses rather than a rough cloth, which helps the lens coating and frame finish last.
About the Build
The acetate used here comes from renewable wood pulp and cotton fiber rather than standard petroleum-based plastic, which is part of why the brand markets this style as an eco-friendly frame option. The polarized lenses add functional sun protection to a shape designed around soft, flattering angles rather than a strictly technical sport look.
Why Buy From Island Water Sports
Island Water Sports has fitted South Florida customers with sunglasses built for real sun and salt since 1978. We stock the Sito Diamond Polarized Sunglasses because the polarization and eco-conscious build hold up to daily coastal wear, not just a showroom shelf.
