Why Why We Choose Acetate for Our Eyewear...

... and what it means for our oceans
by the Wai-Lā Team
At Wai-Lā, everything we create is shaped by the same force that inspired us to begin: the ocean. Its colour, its rhythm, its quiet power. So when we designed our eyewear collection, we asked ourselves the same question we ask with every product — how do we make something beautiful without costing the sea something precious?
The answer was acetate. And once you understand what it is and where it comes from, we think you’ll love it as much as we do.
What Is Acetate, Exactly?
Acetate — or cellulose acetate, to give it its full name — is a plant-based material derived primarily from cotton linters (the short fibres left over after cotton has been harvested) and sometimes sustainably sourced wood pulp. It has been used in eyewear for decades, prized by craftspeople for its rich depth of colour, its natural sheen, and the way it can be shaped with incredible precision.
Unlike the ordinary plastic frames you might find at a petrol station, acetate isn’t a petroleum-derived synthetic. It starts its life in a field, not a refinery. That distinction matters enormously when we talk about what happens at the end of the life of a pair of sunshades — and what happens if it ever finds its way somewhere it shouldn’t.
The Problem with Conventional Plastic Eyewear
Conventional eyewear frames are typically made from petroleum-based plastics — nylon, polycarbonate, or propionate blends. These materials are durable, yes, but they come with a hidden cost.
Petroleum-based plastics do not biodegrade. They break down into smaller and smaller fragments — microplastics — that work their way into waterways, into marine ecosystems, and ultimately into the food chain. A discarded pair of regular plastic sunglasses left on a beach doesn’t disappear. It persists for hundreds of years, fragmenting silently, invisibly, harmfully.
The fashion and accessories industry contributes significantly to plastic pollution in our oceans. Billions of pieces of plastic enter the sea every year, and eyewear — so often treated as a seasonal, disposable accessory — is part of that story.
We didn’t want to be part of that story.
How Acetate Helps Protect the Ocean
It’s Biodegradable
Because cellulose acetate is derived from natural plant cellulose rather than fossil fuels, it is biodegradable under the right conditions. Soil microbes and moisture can break it down over time — a fundamental difference from petroleum plastics, which simply cannot be processed by nature in any meaningful timeframe.
This means that if an acetate frame ever does end up in the environment — in a landfill, on a riverbank, caught in the tide — it won’t persist indefinitely. It won’t spend centuries fragmenting into microplastics. Nature can, over time, reclaim it. That is not a small thing.
It Reduces Microplastic Risk
Microplastics are one of the most pressing threats facing marine ecosystems today. These particles — smaller than 5mm, often invisible to the naked eye — have been found in the deepest ocean trenches, in Arctic sea ice, in the bodies of fish, seabirds, and marine mammals. Studies have found them in human blood.
The primary source of microplastics in our oceans is the degradation of conventional plastic products. By choosing a material that biodegrades rather than fragments, we are actively reducing the risk of our eyewear contributing to this crisis. Acetate doesn’t shed the kind of persistent synthetic microparticles that end up coating the ocean floor and entering marine food webs.
It’s Made from Waste, Not Resources
Here’s something we love about acetate that often goes unnoticed: the cotton linters used to produce it are agricultural by-products. They are the short, fine fibres left on the cotton seed after the long fibres have been harvested for textile production. Without a use, they would simply be discarded.
Cellulose acetate gives those leftover fibres a second life. It transforms what would otherwise be agricultural waste into a high-quality, long-lasting material. There’s a beautiful circularity in that — waste becoming something worth wearing, something that connects you to the coast.
It Lasts
Sustainability isn’t only about end-of-life. It’s also about longevity. A frame that lasts five years is, by definition, five times better for the planet than one that lasts one.
Acetate is exceptionally durable. It holds its shape, resists fading, and develops a beautiful patina over time rather than degrading aesthetically. Our frames are designed to be worn season after season — through salt spray and sun cream and summer after summer. The more you wear them, the more they become yours. That’s the opposite of a disposable product, and that’s exactly the point.
Quality You Can Feel, Conscience You Can Carry
There’s something else worth saying. Acetate simply feels different. It has a warmth and weight that synthetic plastic can’t replicate. The colours are richer — because the pigment is held within the material itself, not painted on top. The finish is smoother. The craftsmanship is visible.
When you hold a pair of Wai-La frames, you’re holding something made with intention. Chosen not just because it looks beautiful against sunlit water, but because it was the right decision — for the product, for you, and for the ocean we are all drawn to.
Our Commitment Goes Further
Choosing acetate is one part of how we think about our environmental responsibility at Wai-Lā. We believe that swimwear and coastal lifestyle brands have a particular obligation to the oceans that inspire them. The sea gives us our aesthetic, our identity, our love of what we do. The very least we can do is refuse to harm it.
That means making considered material choices at every stage. It means thinking about packaging, about production, about longevity. It means asking, every time, whether there is a better way.
Acetate is one of our answers. It won’t be the last.
