OUR MATERIALS


At ECO SHADES, materials are the foundation of every design. Each pair of sunglasses is developed using a curated mix of recycled or plant-based materials, combined with high-performance components - chosen for their quality, comfort, and durability.
Biodegradable Acetate
Used in our Biodegradable Collection, this material is currently made from 62% plant-based content (wood pulp and plant-oil) and 38% fossil-based plastic. At this stage, it isn’t possible to make frames 100% plant-based, but development is ongoing. The material offers the same depth, structure, and premium surface feel as traditional acetate, while remaining durable and adjustable.
Recycled rPCTG
rPCTG is a recycled plastic made from industrial and post-consumer waste. Strong, clear, and BPA-free, it is used in the fronts of many of our styles from our Recycled Collection. The material gives the frame both flexibility and structure, with a smooth, high-quality finish that lasts.
Recycled TR90 (rTR)
TR90 is widely known in the optical industry for being extremely lightweight, flexible, and resistant to deformation. We use recycled TR90 in select styles such as VORK and GROSSO - ideal for frames that need to feel light on the face while maintaining their shape.
Recycled CP (rCP)
All ECO SHADES styles with rPCTG fronts, are fitted with temples made from recycled cellulose propionate. Soft to the touch and easy to adjust. It creates a secure, comfortable fit designed for all-day wear.
100% Recycled Lenses (rPMMA)
All lenses in the ECO SHADES collections are made from 100% recycled rPMMA, a high-quality acrylic material. They provide full UV400 protection, crystal-clear vision, and strong durability. Certified to international optical safety standards.
Stainless Steel Metal Cores
Inside each temple is a stainless steel core that adds strength and allows the temple to be adjusted for a precise fit. Recycled steel is not yet consistent enough for this use, so we opt for stainless to guarantee quality and long-term stability.
Friction-Lock Screws
Our optical-grade 5-barrel hinges are secured with friction-lock screws. Each screw includes a nylon patch to prevent loosening - no glue required. A detail that keeps the hinge firm through daily wear.
