Photochromic Polarized Sunglasses UV400
Description
Smart Lenses, Adapt to Light
These photochromic lenses automatically darken in bright sunlight and clear up indoors or at night — giving you perfect vision in any environment without switching glasses.

UV400 Polarized Protection
100% UV protection blocks UVA, UVB, and UVC rays. Polarized lenses eliminate 99% of glare from water, roads, sand, and snow — keeping your eyes safe and comfortable all day.

Works Day and Night
At night, lenses stay light and transparent to enhance visibility while reducing glare. During the day, they filter strong light, reduce eye fatigue, and sharpen your vision.
Built for Outdoor Activities
Driving, running, fishing, cycling, hiking — these glasses handle it all. The photochromic lenses adapt instantly so you can stay focused on what matters, not your eyewear.

Lightweight Alloy Frame
Crafted from high-strength Al-Mg alloy — durable yet featherlight. Adjustable temples, flexible arms, and ergonomic nose pads ensure a secure, comfortable fit for all-day wear.
5 Lens Colors Available
Choose from Photochromic Black, Black, Blue, Orange, or Yellow (Night) lenses — each paired with a sleek black frame. Optional leather eyeglass case available.

How to Test Photochromic Effect
Place the lenses under direct sunlight for 10–15 seconds — they will darken noticeably. Note: the effect requires UV radiation to activate and does not work indoors or in cloudy weather.
