What is a HUD, anyway?

A head-up display projects information — your speed, navigation, blind-spot alerts, lane departure warnings — onto the windshield directly in your line of sight. The image is created by a small projector below the dash that bounces polarized light off the windshield into your eyes.

HUDs first showed up in fighter jets and BMW 5-Series cars. Today they're standard or optional in dozens of vehicles, from Mazda 3s to Ford F-150s to Tesla Model 3s. If your car is from 2020 or newer and has any kind of "premium" or "tech" trim, there's a good chance it has one.

Why polarized sunglasses break the HUD

The same physics that makes polarized sunglasses excellent at cutting glare off water also makes them incompatible with HUDs. Both rely on filtering light along a specific orientation. When the orientations clash, the light gets blocked.

Polarized + HUD

The HUD's polarized projection passes through the windshield, hits your polarized lens at the wrong angle, and gets canceled out. You see a faint rainbow ghost where the speedometer should be — or nothing at all. Tilt your head and the image flickers in and out.

Non-polarized + HUD

Light passes through the lens unfiltered. The HUD image stays sharp, contrasty, and readable at every head angle. You still get UV400 protection, glare reduction (via tint and AR coating), and full color contrast. You don't get the rainbow ghost.

The cleanest way to verify the problem is to put on a polarized pair, sit in a HUD-equipped car, and tilt your head 30 degrees to one side. The HUD image will dim, color-shift to a rainbow oil-slick, or vanish entirely. Repeat the test in a non-polarized pair: the image stays put.

Cars that ship with HUDs in 2026

This is a partial list — most luxury and mid-luxury makes offer HUDs as a tech-package upgrade across multiple trims. If your car is from one of these manufacturers and has a "Premium," "Technology," "Executive," or similar package, it likely has a HUD. Check your owner's manual under "instrument cluster" or "head-up display."

How to tell if your sunglasses are polarized

Most polarized sunglasses don't shout it from the temple. To check, do one of these tests:

1
The phone test. Hold your sunglasses in front of your phone screen and rotate them 90 degrees. If the screen darkens dramatically or turns black at one rotation, the lenses are polarized.
2
The two-pair test. If you have another known-polarized pair, hold the lenses perpendicular and look through both. Polarized + polarized at 90 degrees = blackout.
3
The label test. Look on the inside of one temple or on the original tag. Most polarized lenses are explicitly labeled "POLARIZED" or "P" near the lens etchings.
4
The HUD test. Sit in a HUD-equipped car, put on the sunglasses, and tilt your head left and right. If the projected speed/nav image dims, ghosts, or rainbows out, your lenses are polarized.

HUDDYS' position

Every HUDDYS lens is non-polarized. Every. Frame. We don't make a polarized version, we don't offer it as an upgrade, we don't have a tactical line that switches it on. The brand exists because polarized was the wrong default for drivers in HUD cars, and we'd rather build for the future than the past.

You still get UV400 protection (the part that actually matters for eye health), a gradient or smoke tint that cuts brightness, hard coat for scratch resistance, back-surface AR to kill reflections, and hydrophobic / oleophobic coating for fingerprints and rain. The only thing missing is the polarization filter that breaks your dashboard.

Built for the dash. Cut to wear after.

Edition 01 is seven silhouettes, all non-polarized, all UV400. Pre-order opens soon — first fifty get $20 off.
