Frequently Asked Questions

Q: What does "photochromic" mean for these cycling glasses?

A: Photochromic lenses contain special compounds that react to UV light. When you ride in bright sunlight, the lenses automatically darken to reduce glare and eye strain. In shaded or low-light conditions, they quickly lighten again to maintain clear visibility — all without you needing to swap lenses.

Q: Are these glasses suitable for both road cycling and mountain biking?

A: Absolutely. The wraparound design, UV400 polarized lenses, and photochromic technology make these glasses a great fit for road cyclists, MTB riders, trail bikers, and general outdoor sports enthusiasts alike.

Q: Do these cycling glasses fit both men and women?

A: Yes! These glasses are designed with a unisex fit, making them comfortable and secure for a wide range of face shapes and sizes, regardless of gender.

Q: What is UV400 protection and why does it matter?

A: UV400 is the highest standard of UV protection available in eyewear, blocking all light rays with wavelengths up to 400 nanometers — covering the full spectrum of UVA and UVB radiation. This helps safeguard your eyes from long-term UV exposure during outdoor activities.
