What the IRX lens is made to do.

How facial recognition actually reads you

Cameras don't "see" a face the way a person does. Software measures it. Most systems lean on three things:

Geometry. The distances between landmarks: how far apart your eyes are, the width and length of your nose, the line of your brow and jaw. Together those numbers become a model of your face.

Symmetry. Faces are close to symmetrical, so algorithms check that landmarks line up on both sides. The cleaner the match, the higher the confidence score.

Shading and reflection. This is the part most people miss. Many cameras don't rely on visible light alone. They throw out near-infrared light and measure how it bounces off skin, bone and the eyes. That's how they get a sharp face at night, in shade, or through a windshield.

Why hats and regular sunglasses only get you halfway

A brim and dark lenses do help. They hide landmarks and add shadow. But ordinary sunglasses only block visible light. Switch the camera to infrared and the lenses go see-through, the eyes show up clearly, and the software rebuilds your face from the IR image anyway.

To a person, your sunglasses look dark. To an infrared camera, they're barely there.

The band that matters: near-infrared

Near-infrared runs from roughly 780 to 1,400 nanometers. You can't see it, cheap IR illuminators are built into most security cameras, and almost no consumer eyewear filters it.

The IRX lens uses selective wavelength filtering. It cuts near-infrared transmission by 99%+, shifts the contrast and shading around the eyes in visible light, and makes the eye landmarks a lot less consistent frame to frame. It filters specific wavelengths instead of blocking everything, so you can still see clearly enough for everyday wear.

The result is a face that's less consistent, less symmetrical and harder to model for the consumer-grade and commercial systems you walk past every day. IRX also blocks 99%+ of UV and cuts blue light.

Get the most out of your pair

• Wear them fully seated on your face, not pushed down your nose.
• Add a hat or brim when you can.
• Don't stand right under fixed cameras, and don't linger in view.
• Keep your head angle natural. Looking straight up at a camera gives it the best shot.

What Stocklens is, and isn't

It is everyday eyewear designed to lower what cameras can get from your face, built for regular people, and most effective as one layer among a few good habits.

It isn't an invisibility cloak, military or law-enforcement gear, or a guarantee against every system out there. Results depend on the camera, the lighting and the angle.
