Key Benefits
Advanced FD Film Photochromic Technology:** Experience the next level of light adaptation. The 3rd generation FD film ensures a faster, more uniform color transition that responds instantly to UV intensity, making these glasses truly "day and night" compatible.
HO Double-Curve High-Definition Lenses:** Designed to wrap around the face, the double-curve lens geometry minimizes peripheral distortion and provides an expansive field of view while shielding your eyes from wind, dust, and debris.
Ultra-Lightweight PPSU Memory Material:** The frame is constructed from premium PPSU, a high-performance memory polymer known for its incredible toughness and flexibility. This material allows the glasses to retain their shape while remaining light enough to "disappear" during long-distance runs.
O-40 HD Optical Precision:** See the road with stunning clarity. The O-40 optical technology enhances contrast and sharpens details, significantly reducing eye fatigue during extended outdoor sessions.
Upgraded Adjustable Silicone Fit:** Featuring an improved anti-slip silicone nose pad, these glasses offer a customizable fit that stays secure even during high-intensity movement. The skin-friendly material is resistant to aging and sweat, ensuring long-lasting comfort.

How to Use
Place the sunglasses on your face before heading outdoors. The intelligent lenses do not require manual adjustment; they will automatically darken when exposed to sunlight and clear up in shaded or indoor environments. For a personalized fit, gently pinch or widen the adjustable silicone nose pads to ensure the frame sits securely on your bridge without bouncing during your stride.
Care & Safety
To preserve the specialized FD photochromic film, always store your sunglasses in a protective hard case when not in use. Avoid exposing the lenses to extreme heat, such as a car dashboard in summer, as high temperatures can affect the transition material. Clean the lenses exclusively with a clean microfiber cloth to avoid scratching the high-definition coatings.
Notes
These professional-grade glasses are designed to ensure the lens can "变色更快更均匀" (change color faster and more uniformly) for a superior visual experience in changing light conditions.
