Recycled Coffee & Flax Frames
Coffee Sunglasses
Polarised, UV400 & Just 18g
Sunglasses Made from Coffee Grounds
RUNESILK Coffee Sunglasses have frames made from used coffee grounds, mixed with flax (wheat straw) and a plant-based biopolymer made from vegetable oil. The result is a frame that weighs just 18g, so you barely notice you are wearing them.
Every pair has polarised TAC lenses with UV400 protection, in a choice of three mirrored finishes: blue Aqua Reflection, silver Silvershine and yellow Sunburst.
These are among the last RUNESILK sunglasses. We are retiring our eyewear to focus on beard care, so once this stock is gone, it is gone. Read the story.

Questions
Coffee Sunglasses FAQs
Quick answers about the lenses, the frames and how they fit.
Are coffee sunglasses really made from coffee?
Yes. The frames are made from used coffee grounds mixed with flax (wheat straw) and a biopolymer made from vegetable oil, which is moulded into a block and laser cut to shape.
Are the lenses polarised?
Yes. Every pair has polarised TAC (tri-acetate cellulose) lenses with UV400 protection and a mirrored finish in blue, silver or yellow.
How much do they weigh?
Each pair weighs just 18g, which makes them light enough to wear all day without pressing on your nose or ears.
What size are the frames?
The frames are 145mm wide with 145mm arms, 55mm lenses and a 17mm bridge. Compare those with a pair you already own to check the fit.
Will RUNESILK make more sunglasses?
No. We are retiring our sunglasses to focus on beard care, so these are among the last pairs we will sell. Once they are gone, they will not be restocked.
