Q: What’s the Difference Between Cylindrical and Spherical Lenses?

Cylindrical lenses (like on Vulcans™ and Airas™ ) are flatter and give you a wide, wraparound field of view — perfect for maximum peripheral awareness. Spherical lenses (like on Velans™ and Ultras™ ) curve more naturally around your eye for sharper optical clarity and precision. Both use 8KO® tech, so the final pick is what fits your style and sport best. 🤔 If you're unsure about this pace product to pick, don't hesitate to contact our team of experts via our webform or chat bubble ! Our team will pick up your query within one working day!

Question 1

Will my original Velans Lens fit the Velans 2 frame?

Accepted Answer

In short: no, Velans lenses are not compatible with the Velans 2 frame.

The Velans 2 has been completely re-engineered, including updated lens dimensions and a redesigned frame geometry. This means lenses from the original Velans model won’t fit the new iteration.

If you’re looking to replace your lenses, you can browse our Velans 2 replacement lens kits—designed specifically for a perfect fit and seamless performance with the new frame. 🔁

As part of this evolution, we’ve now officially discontinued the original Velans model. This means we won’t be restocking or producing additional replacement parts for it moving forward.

We know that’s not always ideal, but it allows us to focus fully on pushing performance forward with the Velans 2.

Question 2

Meet the Velans 2

Accepted Answer

The Velans 2 is the evolution of our bestselling, gold medal–winning performance sunglasses—refined over five years and rebuilt with one goal: pushing performance closer to perfection. Developed in collaboration with elite athletes, every detail has been pressure-tested to deliver a more secure fit, clearer vision, and greater durability in the moments that matter most.

At the core of the Velans 2 is a completely remodelled arm and temple profile. Ergonomically tuned internal arm fins maximise grip and stability, adapting comfortably to a wide range of head shapes while staying locked in place during high-intensity movement. Paired with a featherweight yet highly durable frame, they’re designed to feel almost unnoticeable—until you need them most.

👓 Vision is driven by our 8KO® nylon lens technology, offering exceptional optical clarity with high-definition detail, even as light conditions change. The wrap-around lens design provides maximum coverage and protection, while integrated, strategically placed vents ensure continuous airflow to prevent fogging and maintain clarity throughout your effort.

💪 Durability has been rethought from the ground up. Our Pop-Lock™ hinge system removes the need for screws, reducing common points of failure and increasing impact resistance, while also simplifying lens changes. The interchangeable lens system features a quick-release design, allowing you to adapt instantly to shifting environments.

♻️ Sustainability is built into the Velans 2 without compromise. Our Infinite™ frames are constructed from 100% recycled materials, delivering a carbon footprint up to seven times lower than traditional virgin plastic frames—so you can perform with a cleaner conscience.

Designed for seamless integration, the frame geometry ensures full compatibility with helmets, making them ideal for cycling and other performance sports. And with 100% UVA and UVB protection as standard, your vision stays protected in every condition.

Finally, the Velans 2 is backed by our lifetime guarantee. If they break, we’ll fix them—free, forever.

Question 10

Are SunGod Pace products polarised?

Accepted Answer

The SunGod Pace Series lenses are not polarised. After talks with numerous industry professionals and athletes, we determined it's best not to include polarisation on our Pace Series.

Yes, polarisation can be great in lifestyle, however, in performance polarised lenses can reduce contrast, thus reducing terrain visibility. Cyclists, ultra-runners and trail runners need maximum depth perception and clarity, especially on trails or technical courses. 🏃‍♂️

Instead, all SunGod Pace Series lenses feature our 8KO™ lens technology – the most advanced lens technology on the market. Constructed from a nylon-based material that is optically superior and lighter, SunGod 8KO™ lenses are a step above the industry standard polycarbonate lenses. Not only this, SunGod 8KO™ lens technology is hydrophobic and oleophobic, meaning they will repel sweat and water and are wiped clean easily without smudging. 😎

Thanks to 8KO™ lens technology, the SunGod Pace series offers unrivalled clarity and colour definition to offer the clearest view of the road ahead.
