Photochromic Sports Sunglasses with UV400 Protection – Half Frame

A Pair of Glasses for Every Light Condition — From Tunnel Exits to Mountain Peaks.

No more switching between sunglasses and everyday glasses: these photochromic polarized glasses automatically adjust their tint to suit any lighting situation — from clear to dark gray in seconds.

• Photochromic Automatic Tinting: The lenses respond to UV intensity, seamlessly transitioning from clear to dark gray, eliminating the need for manual lens changes while driving, cycling, or hiking.
• UV400 Polarization Filter: Blocks 100% of UVA, UVB, and UVC radiation and eliminates 99% of glare from water, roads, and snow, providing continuous eye protection and significantly reducing eye fatigue.
• Al-Mg Alloy Frame: Aluminum-Magnesium is lighter than standard plastic frames while offering higher rigidity, ensuring a secure fit without pressure, even during extended wear.
• Suitable for Day and Night: In low light, the lenses remain bright and clear for maximum visual acuity while minimizing glare from oncoming traffic or streetlights.
