Core Features

Polarised Glass

Polarized glasses capture light reflections within your field of sight and provide for clearer vision. Light that reaches the eye is dulled and therefore much less blinding. A person’s sight is substantially clearer and sharper. The perception of colors is also improved. Ideal for sunny days in nature ;)

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.

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.
