Polarized sunglasses and HUD problem.

[Viktorv1961]

It can be hard these days to find decent sunglasses that aren’t polarized. FWIW, Ray-Ban is another of the few makers of nice optics that still offers a decent number of non-polarized options with good quality. I bought a couple pairs and just leave them in my vehicles.

Serengeti TELLARO Drivers Gradient Non-Polarized Photochromic fits the bill. Ray-Ban Gradient Aviator is a good choice too.

Side question, anyone know how to clean the HUD projector?

Mine has a lot of dust collecting on it, with my BMW, I asked at the dealership and the detailer I use and both said not to touch it.

In fact the detailer said dust drives him crazy and he understands my desire to clean it, but in his experience, the projector scratches very easily.

There wouldn’t be a setting for this. It is how the light is filtered at the screen or projector setup, whichever method Toyota used to implement a hud. Polarizers restrict light to a certain orientation, which is why rotating a lens with polarization changes the behavior. There have been newer HUDs now that don’t rely on a polarizing filter and therefor don’t really interfere with people wearing glasses with polarization, but it is not the one used in our vehicles. And even then, not all polarized glasses would be affected, just depends on how it is set up in those glasses and the orientation of the light to them.

Rough idea behind it all.

Toyota likely doesn't use a polarizer at all. The nature of reflected light is that it becomes polarized.

When I clean the interior of my windshield, I put something over the HUD projector screen to keep it dry. I typically only clean the actual projector about twice a year and use a very light touch with a slightly dampened microfiber towel (a light spray of Invisible Glass on a Dry Me a River towel works nicely.)
