COLORFUL HD POLARIZED UV400 LENSES: UV400 blocks 100% UVA and UVB rays. Colorful HD polarized lenses restore true color with a density coating that preserves original colors, improves visual clarity and contrast, and reduces reflected and scattered light. This helps scenery appear clearer and softer while providing eye protection. QUALITY TAC AND PC MATERIAL: Lenses are made from shatterproof TAC material for durability during prolonged wear. The lightweight PC frame design makes them ideal for motorcycle and cycling, driving, running, fishing, racing, skiing, climbing, trekking, and other outdoor activities. They are scratch resistant, unbreakable, and built for maximum performance in tough conditions. SPECIAL RIMLESS JACKET WITH SOFT ANTISLIP RUBBER NOSE PAD: Rimless jacket frame enables a clear lower vision field. Fashionable design with rich color combinations of frames and lenses. Soft antislip rubber nose pad prevents sunglasses from slipping when sweating and provides a comfortable, secure fit. Suitable as sport sunglasses for men and women. COLORFUL PHOTOCHROMIC LENSES: Lenses transition from clear to colorful in response to ultraviolet intensity, with light transmission changing from 85% (clear) to 15% (dark). They darken automatically under UV exposure to protect eyes from sunlight and glare, and softly to clear indoors. The gradual transition helps reduce eye fatigue from rapid changes in light. Use scenarios: Ideal for motorcycle or bicycle riding, driving, and running in varying light conditions. Suitable for outdoor activities such as fishing, racing, skiing, climbing, and trekking.
