KAPVOE K63 is built for routes where light intensity changes and a fixed lens would be less versatile. The integrated PC photochromic lens responds to outdoor UV, becoming darker as exposure rises and returning toward a clearer state as UV falls; its range is CAT.0-CAT.2. The lens is fixed rather than interchangeable. Vent openings in the lens promote airflow and help reduce fog buildup during hard efforts or temperature changes. A flexible TR90 frame and soft rubber nose pad support comfortable contact during movement. UV400 with 99.99% UVA/UVB filtering supports daytime outdoor use, while the photochromic response continues into dusk, low light and night riding. Designed for cycling, MTB, running and hiking.
