Acetate sunglasses have frames made from cellulose acetate, a plant-based plastic made mainly from wood pulp and cotton. It's known for rich, deep colour, a polished finish and a comfortable weight, which is why it's a popular choice for quality frames.
If you've ever wondered why two black frames can look and feel so different, the material is often the reason. Here's what acetate is, how it compares with other frame materials, and whether it's worth paying a little more for.
What is cellulose acetate?
Cellulose is the natural fibre that gives plants their structure. To make acetate, cellulose from sources such as wood pulp and cotton is processed into a tough, flexible plastic. For eyewear, it's made into sheets or blocks, with the colour and pattern built into the material itself.
You'll see it called "cellulose acetate" or simply "acetate". They're the same thing. Every Yume frame is made from acetate.
Why acetate frames look different
Acetate frames are cut from those sheets or blocks, then shaped and polished. Because the colour runs through the material, rather than being painted on the surface, you get:
- Depth of colour: patterns like tortoiseshell have real depth. Hold a pair up to the light and you can see into the colour.
- A polished finish: acetate takes a smooth, glossy shine, and it can also be given a matte finish.
- Colour that won't flake off: there's no painted layer on the surface to chip or wear away.
Our Aurien Tortoiseshell is a good example, with a thick acetate front that shows off the pattern. For a softer look, the Velora Matte Black shows how acetate can be finished without the shine. See more patterns in our tortoiseshell sunglasses.
Acetate also gives designers room to play with thickness. It can be cut into a chunky, flat-topped front like Celuna, or into slim arms like Lucid. Many Yume frames add small metal details too, such as the three silver studs at each hinge on Aurien and the star-shaped rivets on Noema.
Acetate vs other frame materials
| Material | How it's made | What it's like |
|---|---|---|
| Acetate | Cut from sheets or blocks of cellulose acetate | Deep colour, polished finish, comfortable weight, can be adjusted with gentle heat by an optician |
| Injection-moulded plastic | Melted plastic shaped in a mould | Cheaper and lighter, with colour often sprayed on |
| Metal | Shaped from metal parts | A thinner, more minimal look |
Injection-moulded frames are fine for a budget pair, but they don't usually match acetate for depth of colour or finish. Metal frames suit a slim, light look, while acetate is the natural choice for bolder shapes and richer colours.
The pros and cons of acetate
Pros
- Rich colour and pattern that run through the frame
- A smooth, polished finish
- A comfortable, solid weight that feels well made
- Can be adjusted with gentle heat by an optician for a better fit
- Works for chunky, statement shapes as well as slimmer styles
Cons
- Usually costs more than injection-moulded plastic
- Slightly heavier than the lightest plastic frames
- Heat can warp it, so it shouldn't be left on a car dashboard or anywhere hot
- Needs a little care to keep its shine
None of the downsides are a big deal with sensible care. Our guide on how to clean and care for acetate sunglasses covers everything you need.
Are acetate sunglasses worth it?
If you wear sunglasses often, yes. You get a frame that looks richer, feels more substantial and can be adjusted to fit you better. Look after a good acetate pair and it can last for years.
If you tend to lose a pair every summer, a cheap frame might make more sense. But if you want one pair you'll reach for every day, acetate is a smart choice. Yume frames start from £45, and every pair has UV400 lenses and comes with a hard case and a microfibre cleaning cloth. If you like a bold look, our chunky sunglasses show acetate at its best.
FAQs
Is acetate better than plastic?
Acetate is a type of plastic, but it's made differently from cheaper injection-moulded frames. It usually has deeper colour and a better finish, and it can be adjusted by an optician.
Is tortoiseshell the same as acetate?
No. Tortoiseshell is a pattern, and acetate is a material. Our tortoiseshell frames are made from acetate, like all Yume frames.
Can acetate sunglasses be adjusted?
Yes. An optician can warm acetate gently to adjust the fit. Don't try it at home, as too much heat can warp the frame.
Are all Yume sunglasses made from acetate?
Yes. Every Yume frame is acetate, and every pair has UV400 lenses.
