KAPVOE Photochromic Sports TR90 PC Photochromic UV400 for Men and Cycling Marathon Mountain Outdoor Night Windproof Sunglasses, Ultra-Lightweight,

[PC Photochromic Lenses] These sports sunglasses feature photochromic lenses that change color in response to UV rays. This allows them to be used as sports glasses, providing clear vision in any weather. When exposed to strong, direct sunlight, the lens transmittance drops sharply from 85% to 15%, activating in response to UV rays. This reduces glare and protects your eyes from harmful UV rays. When you move indoors or to a place with lower light levels, the lenses naturally return to their clear state. 【UV400 Protection】KAPVOE photochromic glasses (unisex) are constructed with durable TR90 frames and shatter-resistant polycarbonate lenses. All lenses have UV400 protection, effectively blocking harmful UVA and UVB rays. The lenses also feature an anti-reflective coating to reduce glare and provide clear, comfortable vision, which is especially important for sports sunglasses. 【Adjustable No-Slip Silicone】The adjustable nose pads of these glasses are made of soft, skin-friendly silicone, allowing for a perfect fit for different nose shapes while increasing friction to keep the lenses securely in place. The no-slip rubber temple arms have a textured design that provides a snug fit even in humid conditions, allowing you to enjoy vigorous activities without worrying about your glasses slipping off. [Frameless Lightweight Design] These sunglasses feature a lightweight frameless design, weighing just 22 grams per pair. This design provides a wider field of view and reduced weight, allowing for greater freedom of movement. The durable TR90 frame construction ensures reliability in a wide variety of extreme environments, and the frameless design avoids impact during high-performance activities. They are ideal as clear polarized sports glasses. 【Multifunctional Use】These glasses are not only suitable for various weather conditions but also meet the diverse demands of outdoor activities, including cycling, baseball, mountain biking, driving, fishing, golf, hiking, etc. Photochromic technology makes them an ideal partner for sports enthusiasts and outdoor adventurers, allowing you to enjoy clear sports glasses in any environment. 【Photochromic Sports Sunglasses】One lens is enough for day and night. PC photochromic lenses automatically change from light to dark depending on the intensity of UV rays.
