Brehn | Polarized Photochromic Sunglasses | UV400 Protection | Automatic Light Adjustment (Day and Night) | Intelligent Glare Reduction for Drivers and Outdoor Activities

Adaptive optics & advanced light filtration

The Vivolux photochromic sunglasses are a high-performance technical solution for variable light conditions. The system uses light-sensitive lens technology that adjusts the darkening level in real time to the intensity of UV rays. Indoors or at dusk, the lenses remain almost transparent, while darkening within seconds in direct sunlight. This ensures consistent visual acceptance without the need to manually change glasses.

Technical features & protection functions

• Polarizing filter: The integrated polarization layer eliminates reflected glare from horizontal surfaces such as wet roads, snow, or water. This increases contrast and significantly reduces eye strain.
• UV400 protection: Provides full protection against UVA, UVB, and UVC rays up to a wavelength of 400 nanometers.
• Photochromic reaction speed: The lenses feature a highly efficient coating that allows rapid transition between filter categories (Cat. 0 to Cat. 3).
• Lightweight and sturdy construction: The frame is designed for durability and ergonomic comfort, ideal for extended use during driving, cycling, or hiking.

Application profiles:

Thanks to hybrid properties, the glasses are optimized for 24-hour use:

• Day: Full sun protection and minimization of glare in bright daylight.
• Dusk/Night: Brightening effect and reduction of annoying light reflections from oncoming vehicles thanks to the polarizing filter.

Technical specifications:

Note: Slight optical and dimensional variations may occur in the actual product due to lighting, shooting angle, and individual screen settings.
