Each lens clicks into the frame with a flexible retention channel. To remove a lens, press it inward slightly to release the clip, then lift it out. Seat the new lens by aligning the top edge and pressing gently until both sides click. No screwdriver, no heat, no service visit.

Yes. The front and temples are designed to separate and reconnect by hand. Align the temple hinge with the front receiver, press until you feel a firm click, then give it a light tug to confirm it is locked. The same motion lets you rebuild the glasses in a new colorway in under a minute.

No. The retention system is built to hold the same tension through repeated swaps. You should hear a distinct click when the lens is fully seated. If a lens ever feels soft, re-seat it and confirm the click on both sides.

The TR90 thermoplastic and aluminium hardware are rated for frequent changes. Swap lenses daily or change the frame color for different events — the system is designed for it.

Every $179 system includes two complete frames, two lens sets, a structured hard case and a microfiber cleaning pouch. That is enough to build two looks right out of the box.
