What’s the difference between TR90 frames and ordinary plastic frames?

TR90 is a memory polymer material that’s50% lighterthan traditional plastic, highly flexible (can withstand strong bending without deformation), and resistant to heat/sweat corrosion. It ensures long-term comfort without nose pressure or slipping, making it ideal for sports.

What are the main advantages of TAC lenses compared to regular lenses?

TAC (Triacetate Cellulose) lenses feature multi-layer optical coatings with92% light transmittance, blocking UV400 and glare effectively. They’re impact-resistant (meeting EU/US safety standards) and more scratch-resistant than standard PC lenses, ensuring lasting clarity.

What scenarios are the 5 interchangeable lenses suitable for, and how do I replace them quickly?
  • Clear Lens: Night rides, indoor training, or low-light conditions (enhances visibility);
  • Light Gray Lens: Cloudy days (boosts contrast without over-dimming);
  • Dark Gray Lens: Bright sunny days (reduces glare uniformly without color distortion);
  • Amber Lens: Foggy, dusk, or forest environments (enhances color saturation and depth perception);
  • Mirror Lens: Urban commuting or fashion styling (stylish look with protective functions).Replacement Method: The frame uses a spring-loaded snap design. Gently press both temple joints to remove the old lens, align the new lens with the slots, and snap it into place until it clicks (takes just 5 seconds).
Is the glasses comfortable for long hours? Will they press on the nose or slip off?

The ergonomic curved design, combined with silicone anti-slip pads on the nose bridge and temple tips, adapts to various face shapes and head sizes. Tested for 4+ hours of continuous wear with no discomfort, and it stays secure during intense movements (e.g., mountain biking) with minimal wind resistance.

Are the lenses fog-resistant? Can they be used in the rain?

Lenses come with adefault anti-fog coating(reduces fogging in cold environments). For high-humidity rides, pair with a vented helmet. In rain, useclear or light gray lensesto enhance visibility through water droplets, and wipe the lenses promptly for optimal clarity.
