The Lumen sunglasses combine a lightweight unisex ebony wood frame with polarised UV400 lenses and a clean, modern shape. With a 141 mm frame width and a weight of just 24 g, they are comfortable to wear and easy to style with different looks.
The polarised lenses help reduce glare and provide UV400 protection for sunny days, travel, and everyday city wear. Ebony wood and acetate on the temples create a stable, multi-layer construction with natural material character.
Two fabric chains are included — classic black and patterned — so you can easily vary the look of your sunglasses.
Foldable cork case included: the case can be personalised with your own laser engraving.
The Zeitholz Lumen sunglasses come with a 2-year warranty from the date of purchase. If your sunglasses show a manufacturing defect during normal use, we will review the case and repair or replace the product at our discretion.
The warranty may cover lens defects, frame or temple breakage caused by material or workmanship defects, and loose or faulty hinges.
Damage caused by accidents, improper use, scratches, water exposure, normal wear and tear, or unauthorised modifications is not covered by the warranty.
If you believe your sunglasses have a defect covered under this warranty, please contact our customer service team.
At Zeitholz, we pay attention to the details — from the design of our sunglasses to the use of natural materials and packaging that uses paper and cardboard where possible.
Wood is a natural material with its own grain, colour and structure. This gives every Lumen pair of sunglasses its own individual character.
For every product sold, we plant one tree through our partnership with Trees for the Future. The organisation supports reforestation and agroforestry projects designed to strengthen local communities over the long term.
Every order includes your own Tree Passport — a personalised certificate with information about where your tree was planted, the tree species, and the project it belongs to.
