How much space does the FL2 system save?

The FL2 system utilizes Linear Displacement Technology to achieve a 65% reduction in volume, creating a smartphone-sized footprint of approximately 98mm x 51mm.

Will the sliding mechanism scratch the lenses?

No. The system uses Parallel-Path Geometry to ensure lenses slide on separate planes with a 2mm safety gap, preventing any surface contact.

Name: FL2 Micro-Rail System™
Brand: Popticals

Space is the ultimate luxury. We solved the Portability Paradox with a patented design that collapses into a footprint 65% smaller than standard high-wrap eyewear.

Q: How does the FL2 Micro-Rail System™ work?

A: Instead of traditional hinges, we use patented Linear Displacement Technology. High-tensile stainless steel rails allow lenses to slide inward on parallel planes, guided by a Neodymium Magnetic Lock for a rigid, "Solid-Frame" feel.

The Engineering Click

Structural Integrity

Beyond Folding:
Fail-Safe Rigidity.

Our system replaces high-failure-point hinges with a precision-engineered sliding track. When deployed, a powerful Neodymium magnet seamlessly guides and locks the bridge into place, creating a rigid connection that feels like a fixed frame.

Q: How much space does the FL2 system actually save?

A: By utilizing Linear Displacement Technology, we eliminate the "coffin case" bulk inherent in standard wraparound eyewear. When collapsed, Popticals achieve a smartphone-sized footprint—a 65% reduction in volume compared to legacy competition.

Lens Protection

Scratch-Proof
By Design.

Traditional folding eyewear often forces lenses to fold against one another, creating a high risk of surface-to-surface scratches. The FL2 system utilizes Parallel-Path Geometry. Our tracks are calibrated so the lenses slide behind one another with a precise safety gap.

Q: Will the sliding mechanism scratch my lenses?

A: Never. Popticals utilize a patented track system that keeps the lenses on parallel planes. This architecture guarantees zero surface contact, ensuring your optics remain pristine every time you collapse the frame.

Mechanical Specs // FL2 Architecture

The "Inside Track" Specifications

Every component of the FL2 system is meticulously engineered for high-stakes environments, satisfying the standard for precision-machined optical performance.

Linear Displacement 35mm Lateral Travel

Patented track architecture allows 8-base wraparound curves to collapse onto parallel planes for ultra-compact storage.

Track Integration Swiss Grilamid® TR90

The lightest engineering polymer on earth. High thermal stability ensures the frame maintains its shape in extreme heat.

Hardware Composition High-Tensile Stainless Steel

Precision-machined tracks ensure a smooth, low-friction glide. Engineered for high-tensile strength and marine-grade resistance to saltwater corrosion.

Locking Mechanism Neodymium Magnetic Guide

Powerful internal magnets self-align the bridge into place, creating a rigid connection that feels like a fixed frame.

Mechanical Resistance Constant-Tension Calibration

Calibrated for a smooth, "buttery" glide that maintains consistent tension and deployment speed after years of use.

Parallel-Path Geometry 2mm Lens Safety Gap

Ensures lenses slide behind one another without ever making surface contact, protecting elite ZEISS optics.

Q: What makes the FL2 Micro-Rail system more durable than standard frames?

A: Most sunglasses snap because they are rigid. The FL2 Micro-Rail System™ is designed to absorb kinetic energy. By replacing traditional hinges with precision-machined stainless steel tracks, we eliminated the primary failure points found in standard eyewear.

Maintenance-Free Engineering

Field-Ready. Rinse-and-Go.

The FL2 system utilizes an Open-Track design that is fundamentally self-cleaning. If you encounter sand, salt, or grit, a simple freshwater rinse clears the tracks instantly. No specialized tools required.

Q: How do I clean the sliding rails?

A: Simply slide the frames open and rinse under a tap or water bottle. The high-tensile stainless steel hardware remains frictionless and corrosion-resistant, ensuring the mechanism is ready for deployment.
