The Bio-Acetate Arch Brown Demi feature a round frame made from plant-based bio-acetate with unique brown tortoiseshell veining, paired with amber UV400 lenses that provide high-contrast vision and complete protection against UV rays. Weighing just 35 grams and supplied with a hard case and cleaning cloth, these minimalist sunglasses embody Scandinavian design created for everyday wear, season after season.
The Bio-Acetate Arch Brown Demi are unisex round sunglasses featuring a brown tortoiseshell frame with amber, caramel and dark brown veining, unique to each pair. The amber lenses continue this warm palette while providing clear, high-contrast vision, even in bright light. The rounded shape, refined by slim arms engraved with the Daniel Wellington name in gold lettering, embodies a minimalist style that suits both round and more angular faces.
- The lightweight bio-acetate frame, made from cellulose acetate and a plant-based plasticiser, reduces environmental impact compared to conventional acetate while retaining the flexibility and durability needed for everyday wear.
- The BPA-free nylon lenses provide full UV400 protection, blocking 100% of UVA and UVB rays. Their amber tint enhances contrast and softens brightness without distorting colour perception.
- Weighing just 35 grams, these sunglasses sit comfortably on the face without pressing on the temples or slipping down the nose, making them ideal for a day on the terrace or a stroll around town.
- Each pair comes with a branded hard case, a fabric pouch and a cleaning cloth, to protect the lenses and frame during transport or storage.
An accessory designed to be worn effortlessly, from morning to evening, season after season. This is the very definition of Scandinavian design applied to sunglasses: nothing superfluous, everything that matters.

MEASURING TIPS
You can easily measure the lens width at home in two simple steps, all you need is measuring tape.
STEP 1. USE A MEASURING TAPE
Place the measuring tape between your eyes and measure the bridge width. From either side of this, measure the lens width.
STEP 2. MEASURE YOUR SIZE
Try the different lens measurements and make a note of the one you think is right for you.
WHAT IS A LENS, BRIDGE, FRAME AND TEMPLE?
1) LENS
The lens measurement is the width of the lens, measured from the bridge.
2) BRIDGE
The bridge measurement is the distance between the lenses.
3) FRAME
The frame measurement is the width of the front, from temple to temple
4) TEMPLE
The temple length is the measurement of the 'arms' of the frame.
HOW DO I FIND MY SIZE
Some glasses have the size measurement printed on the inside of the temples. This usually consists of three numbers. Our glasses for example, have 60-12-140 (lens-bridge-temple), but sometimes other brands only print the first two. If you already wear glasses, we recommend you use them as a size reference.
