One lens for changing light. Featuring photochromic adaptive tint technology, this lens transitions from clear to blue as UV exposure increases - maintaining 35% average VLT for consistent visibility from first chair to final lap. Engineered for mixed conditions, storm breaks, and long days on variable terrain, it automatically adjusts to keep your vision sharp when the light shifts.
