Core Features

UV 400

Whether you’re on the beach, in the city or snowboarding on the mountain tops, with your Holzkern sunglasses you are always optimally protected. Sunglasses with UV 400 protection prevent all UV rays with wavelengths between 280 to 400 nanometers from reaching your eyes. With these kinds of sunglasses, all ultraviolet A, B and C rays that are dangerous for the eye are blocked.

Leadwood

Leadwood

Pure elegance for eternity. The grain of leadwood runs unobtrusively through the entire wood and gives this raw material a particularly elegant appearance. Leadwood also impresses with its high density and associated stability. A robust material that promises our natural products a particularly long lifespan and timeless appearance.

TAC Lenses

An additional feature that adds even more quality to our sunglasses is the polarized TAC lenses. TAC is short for “Triacetate Cellulose” and it describes an incredibly lightweight and robust material that can be used on the lenses as well as the frame. It is composed of 7 layers and its production is particularly compley, because the original material consists mainly of cotton or beech tree wood.

Anti-Reflective Coating (AR Coating)

The anti-reflective coating of our glasses reduces the visible light for the eye and provides protection against glare. The glare-protection factor is divided into different categories and glasses are conceptualized for particular light circumstances. The calculation for the respective category can be found on the inside of the glasses. A glare-protection factor of 3 (out of 4) comes with this model, meaning it has a transparency of 8 to 18 percent, and the sunglasses are very well suited for sunny regions, bright water surfaces, the beach and the mountains.
