【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】All KAPVOE lenses provide UV400 protection (blocks 99.9% of UVA/UVB rays) for everyday outdoor and sports use. 【TR90 Frame & Prescription Insert】Lightweight yet strong, stress-resistant TR90 frame keeps the total weight at about 34g. Includes a prescription insert (lenses not included); lenses must be made separately. Enjoy cycling and outdoor sports. 【Non-Slip Rubber Nose Pads】Soft, grippy rubber nose pads provide a secure, comfortable fit. They stay in place even when you sweat or during intense rides. 【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.
