KAPVOE Photochromic Sunglasses Cycling Glasses Men Women Mountain Bike MTB Bicycle Clear Black 01

【Photochromic】UV-activated photochromic lenses adjust to UV intensity: darker in strong UV and clearer in weak UV. Automatic adjustment means no manual lens swapping—one lens for daytime and evening. More convenient in changing conditions (sunny/cloudy, shaded trails/open roads). 【UV400 Protection & Breathable Design】All KAPVOE lenses provide UV400 protection (blocks 99.9% of UVA/UVB rays) for everyday outdoor and sports use. Vent holes on both sides increase airflow and help dissipate heat, reducing fogging for smoother, clearer riding. 【3-Position Adjustable Nose Pad】These MTB glasses include a soft rubber nose pad with 3 adjustment positions to help you find the right angle. They stay secure even during intense training. Lens vent holes promote airflow to help you stay cooler while riding. 【TR90 Frame & Clip-In Prescription Insert】Ultra-light, durable TR90 frame with flexible temples and non-slip rubber at key contact points for a more secure fit. Includes a clip-in prescription insert (lenses not included)—lenses must be made separately. 【Multi-Sport Use】Great for cycling, motorcycle riding, running, skiing, baseball, volleyball, tennis, driving, triathlon, fishing, racing, climbing, softball, hiking, golf, boating, hunting, and more outdoor activities.
