Sunglasses TIFOSI RAIL blackout — interchangeable lenses Smoke 15.4%, AC Red 41.4%, Clear 95.6%

TIFOSI RAIL blackout are sport sunglasses designed for cycling and outdoor activities. The model comes with an interchangeable three‑lens set: Smoke (15.4% visible light transmission) for bright sunlight, AC Red (41.4% VLT) for mixed or variable light conditions, and Clear (95.6% VLT) for low‑light or indoor use. The wraparound lens profile and lightweight frame provide broad coverage and stable fit during movement, while the interchangeable lens system enables quick adaptation to changing lighting without carrying multiple pairs.

The wraparound design enhances peripheral protection from wind and debris while maintaining a comfortable, secure fit for active sports.

Regularly clean lenses with a microfiber cloth and mild lens cleaner to maintain optical clarity; avoid rough fabrics and household cleaners that can damage coatings. Store the sunglasses with the spare lenses in a protective case and change lenses before entering a drastically different light environment to maintain optimal visibility and eye protection.
