Prescription Inserts

Run and see clearly

We can now fit a custom prescription insert to the Re.flex. Each one is cut and fitted to your prescription by our local Sydney lens technician, so you get your own script behind the same no bounce fit.

  1. Add the insert to your order. Pick it up here or on the insert page.
  2. We email you for your prescription. Including your PD. We give you a note you can forward straight to your optometrist.
  3. Your lenses get made. Your sunglasses and your insert travel separately, so they may arrive on different days.

Because every insert is made to your individual prescription, we can't offer refunds or returns on inserts unless they arrive damaged. Anything not right, email us and we'll sort it out.

One lens. Dawn to midday.

Same lens, two lights: near clear with no sun, dark and polarised in full sun.

  • Photochromic
  • Polarised
  • Anti-fog
  • Night contrast
Infinity lens, one side dark in the sun and one side near clear
Engineered for the run

Every part earns its place.

We obsessed over the parts you never think about: the nose pads, the vents, the arms, and especially the lens. Each one solves a problem runners actually have, from bounce to fog to glare. Nothing decorative. Everything does a job.

Most Innovative Lens Tech
Infinity Lens

Most Innovative Lens Tech

The Infinity is our smartest lens. Photochromic, so it shifts tint with the sun: light in low light, dark in full glare. A permanent anti-fog coating keeps your view clear on the hard efforts, and it blocks 100% of UV.

Adjustable Nose Pads
Custom Fit

Adjustable Nose Pads

Bend-to-fit nose pads you can tune to your face, so they sit secure and pressure-free no matter your nose shape, and hold through sweat.

Frameless Design
Flexible Fit

Frameless Design

An open, frameless lower edge keeps the frame ultra-light and lets it flex and move with your face, for an unobstructed field of view and no pressure points.

Featherlight Arms
No Pressure Points

Featherlight Arms

Ultra-light sculpted arms with grippy tips that hold without squeezing. No headache on the long runs, no bounce at pace.

Worn by the community.

You might want to know.

Will Re.flex fit my face?

Re.flex is our lightest small frame, with small coverage, so it suits narrow to average faces. Want to see it next to the others? Compare them without leaving this page.

I have a low nose bridge.

Good news: Re.flex has an adjustable nose piece. Pinch the pads in or out until the frame sits level and clear of your cheeks.

Which lens should I get?

Changing light, early or late runs: Photochromic (Adaptor, or Infinity for polarised, permanent anti-fog and night contrast). Bright sun: Protector.

Can I add my prescription?

Yes. Add a prescription insert above (+$205). After checkout we email you for your prescription and PD, with a note you can forward to your optometrist. Single vision distance only. Made to order, so no refunds unless it arrives damaged.

Can I wear them off the run?

Yes. They suit any active day. Photochromic lenses can even be worn indoors.

Delivery and returns

Ships in 1 to 3 business days. Free shipping over $150. 30-day First-Run Promise: run in them, and if they're not for you, send them back within 30 days, even worn, as long as they're undamaged. Every pair also has a 1-year warranty on manufacturing defects.
