Swift is made for athletes and outdoor movers who want wider coverage with a sharper visual edge. Its oversized shield silhouette provides expanded eye protection, while the lightweight polymer frame keeps the fit comfortable for long rides, runs, training sessions, and bright everyday conditions. The black speckled frame, purple nose pads, and mirrored purple-green lenses create a bold performance look without feeling heavy. Polarized lenses help reduce glare from roads, water, glass, and open outdoor surfaces, while UV protection supports visual comfort under strong sunlight. With a 69 mm lens width and a secure wraparound shape, Swift is a strong choice for cycling, running, hiking, driving, and high-exposure outdoor activities.

Online Prescription Glasses Process

Choosing the Right Lens

Selecting the right lens index depends on your prescription strength (diopters). 
  • 0 to -2.00 diopters (mild prescription): 1.56 index recommended
  • -2.00 to -4.00 diopters (moderate prescription): 1.61 index recommended
  • -4.00 to -6.00 diopters (strong prescription): 1.67 index recommended
  • Above -6.00 diopters (very strong prescription): 1.74 index recommended
Important Note:
* Prescription strength may also be shown as “sphere (SPH)” in your eye test results. For example, -2.00 SPH ≈ -2.00 diopters
* No Prescription (Frame Only): Your glasses will arrive with acrylic demo lenses. These lenses may feature printed brand specifications and are intended solely to maintain the frame's shape. They are not designed for daily wear. We recommend visiting a local optician to have them replaced
* CR39 Index Options: If you select any CR39 option (1.56 - 1.74), your glasses will arrive with premium, crystal-clear optical lenses. These are custom-fitted, free of any printing, and ready for immediate wear

How long does shipping take?

Standard shipping generally takes 5 to 15 business days. Our products are dispatched directly from our facilities in Hong Kong or mainland China. If your order includes customized prescription lenses, please allow an additional 3 business days for our opticians to precisely craft and fit your lenses before the order is shipped.

What if the glasses do not fit?

We offer a 30-day return and exchange policy. If you purchase sunglasses or non-prescription frames, you can return or exchange them within 30 days of receipt, provided they have no obvious signs of wear and are in their original condition.
However, please note that prescription lenses are custom-made to your specific visual requirements; therefore, they are non-refundable and cannot be exchanged once crafted. If you experience any issues with the fit or your new prescription, please reach out to our customer service team, and we will gladly assist you in finding a solution.
