Frequently Asked Questions
What makes the lenses photochromic?
▾
The lenses contain light-sensitive molecules that react to ultraviolet radiation. When UV intensity rises, the molecules darken, increasing tint; when UV drops, they revert to a clear state. This process happens within seconds, providing continuous visual comfort without manual adjustment.
Does the polarization affect color perception?
▾
Polarization primarily removes horizontal glare, but it can slightly alter color saturation. The lenses are designed to maintain true color balance, so most users notice only a modest boost in contrast rather than a significant hue shift, keeping the view natural.
How quickly do the lenses transition between clear and dark?
▾
The photochromic coating reacts to UV light within 10 to 30 seconds, depending on ambient intensity. In bright sunlight the lenses reach full darkness in about 15 seconds, while in moderate light they achieve a comfortable tint in roughly 20 seconds.
Is the frame durable enough for rugged activities?
▾
The frame is made from TR90, a high-toughness polymer known for its flexibility and impact resistance. It can withstand drops, bends, and prolonged pressure without cracking, making it suitable for mountain biking, trail running, and other demanding outdoor extreme sports.
Can I replace the nose pads for a better fit?
▾
Yes, the glasses include three detachable nose pads—small, medium, and large. They snap on and off easily, allowing you to customize the bridge height and pressure. This feature also simplifies cleaning and lets you swap pads if they wear out.
